  • How to upload data to generic ESP8266?
  • Prototype images.
  • How to operate the circuit?

What is an IoT based weather monitoring system?

It is a system that involves in acquiring weather and environment data using advanced electronic sensors and sending them to a web server via internet for real time weather monitoring and storage of data for future analysis and study.  

Why we need an IoT based weather monitoring system?

  • Ease of monitoring your local weather conditions in real time from anywhere in the world.
  • For storing weather and environment data for short and long term for studying weather pattern changes and to understand how human induced climate change affected your local weather.
  • Easy deployment of the setup for monitoring local atmospheric conditions and microclimates for weather forecasting and prediction.

Types of sensors involved in weather monitoring:

We can find wide spectrum of electronic sensors involved in weather monitoring system depending on the kind of application.

For example:

Farmers need to know the temperature, relative humidity, soil moisture, rain fall etc. to enhance their crop production and the following type of sensors are utilized to obtain the data:

  • Temperature sensor.
  • Humidity / hygrometer sensor.
  • Soil moisture sensor.
  • Rain sensor etc.

For an airplane pilot he/she needs to know wind speed, wind direction, atmospheric pressure, precipitation, visibility etc. before they takeoff and they use the following sensors:

  • Barometric sensor – for measuring atmospheric pressure.
  • Anemometer – for measuring wind speed.
  • Rain sensor.
  • Visibility sensor – for measuring visibility during snow, rain, storm etc.

In conclusion, the sensors used for monitoring weather depends on the type application we going to deploy for.

Block diagram of IoT based weather monitoring system:

Block diagram - IoT based weather monitoring system

We are going to develop the weather monitoring system using the above illustrated blocks. The brain of the project is an Arduino board and the surrounding blocks are digital and analog sensors for acquiring local weather and environment data.

A generic ESP8266 is used for interfacing the circuit setup with internet via 2.4 GHz Wi-Fi band. The ESP8266 sends the sensor data to a cloud server where the data gets updated in real time and also gets stored for future analysis. We are utilizing a 16 x 2 LCD display to showcase the sensor data, so that we can observe real-time data locally.

Full circuit diagram for IoT based weather monitoring system:

IoT basIoT based weather monitoring system using Arduinod weather moniotring system using Arduino

The above circuit consists of the following modules:

  • 5V / 3.3V Power supply regulator.
  • Arduino Uno.
  • 16 x 2 display with I2C adapter module.
  • DHT11 temperature & humidity sensor.
  • MQ-135 sensor air quality sensor.
  • BMP180 – Barometric sensor.
  • Light depend resistor (LDR).
  • Generic ESP8266 Wi-Fi module.

Now, let’s explore what each of the module does and how it is interfaced with other modules.

Power supply 5V and 3.3V:

Power supply 5V/3.3V

The above illustrated module takes 9V to 12V DC supply from a wall adapter and converts to 5V and 3.3V for providing power to Arduino board and sensors.

There are multiple 5V and 3.3V supply outputs in this module and you need to connect 5V supply to 5V sensor modules and 3.3V supply to 3.3V sensor modules. Mismatching will lead to malfunction of the respective modules / sensors.   

A button is provided on the module to turn ON/OFF the 5V / 3.3V output. A green LED indicates that the module is powered ON. There is also a USB power output but we won’t be using it for this project.

16 x 2 LCD display:

I2C LCD display

We are utilizing a 16 x 2 LCD display to showcase sensor data locally and it can display 16 alphanumeric characters in 2 rows.

An I2C display module is used in this project to reduce the number of wires that connect from microcontroller to LCD display to four; otherwise we need to connect 16 wires.

I2C display module operates on I2C bus and has the following four pins:

  • SDA – Serial data.
  • SCL – Serial clock.
  • GND – ground.

The Vcc pin connects to 5V of the power supply module and GND connects to GND of the supply, the SDA connects to A4 of Arduino and SCL connects to A5.

The I2C module has backlight control, by removing the jumper we can turn off the backlight and vice-versa. You can adjust the display contrast by rotating the potentiometer (blue color on the module) using a small screw driver.

DHT11 temperature and humidity module:

DHT11 Sensor

DHT11 is a digital sensor responsible for collecting temperature and humidity data from your surroundings. It has three terminals namely:

Vcc connects to 5V supply, GND connects to GND and data pin connects to A0 of Arduino.

Note: The pin diagram for DHT11 module could differ from manufacture to manufacture and it is recommended to take a good look at your module to see which pins are Vcc, GND and Data before you apply power to the circuit.

BMP180 barometric sensor:

BMP180 barometric sensor

The above illustrated module is a barometric sensor which is capable of measuring atmospheric data; it can give out data like, atmospheric pressure at ground level, atmospheric pressure at sea level and altitude.

We will be only extracting atmospheric pressure data at ground and sea level to display it on the LCD, but we will be sending only the atmospheric pressure data at ground level to Thingspeak server, which is the relevant data for your locality.

It has the following pins:

  • Vcc – 3.3V.

Care must be taken while connecting the supply to this module as it operates on 3.3V DC and 5V will kill the module. It operates on I2C bus, same as I2C display adapter module.

MQ-135 air quality sensor module:

case study on weather monitoring system using iot

MQ-135 is an analog air quality sensor which takes air samples from your surroundings and gives out an analog voltage at its output terminal. MQ-135 can detect the following gases:

  • Smoke, CO2 etc.

The operating voltage of MQ-135 is 5V and consumes around 160mA, the sensor has built-in heater for heating the sensor for its normal operation and if the sensor is exposed to strong wind we may get incorrect readings. The sensor takes typically around 3 to 5 minutes to reach optimum temperature depending on surrounding air flow.

The sensor has good sensitivity to detect the above mentioned gases, but the disadvantage is it cannot differentiate which gas or gases have been detected.

Generic ESP8266 module:

Genric ESP8266

The above illustrated module is called generic ESP8266 which is responsible for connecting the weather monitoring system to internet. This module is inserted on a breakout board adapter so that ESP8266 can be interfaced on a breadboard.

Pin diagram of ESP8266:

Pin Diagram of ESP8266

ESP8266 is not a just another ordinary module, it has a full-fledged 32-bit microcontroller which requires a program code to function. We will be using a programmer to upload the code to this ESP8266 module which we will see in the later part of this article. It operates on 3.3V and communicates on serial interface with Arduino.

Light depend resistor – LDR:

Photoresistor

LDR is responsible for collecting data about the intensity of light at your surroundings and it is a passive analog sensor.

The LDR is essentially a resistor that is sensitive to the light, when higher intensity light falls on the photosensitive surface its resistance drops and when less light is received its resistance increases.

In other words, the resistance is inversely proportional to the intensity of the light on the photosensitive surface of LDR. 

This concludes all the modules and sensors used in the circuit setup.

I want the email please sir to communicate with you regarding this project is necessary.

Yes, you can ask you questions here…

Do we need usb cable for data to be transferred to thingspeak , or will it be updated through wifi

Hi, it will be updated through Wi-Fi.

Hlo sir, I am getting error while i try to upload the code.

Hi, Please add all the libraries as mentioned in the post

value_1 = ((value[1] – 0x30) * 10 + (value[2] – 0x30)); value_2 = ((value[3] – 0x30) * 10 + (value[4] – 0x30)); value_3 = ((value[5] – 0x30) * 10000 + (value[6] – 0x30) * 1000 + (value[7] – 0x30) * 100 + (value[8] – 0x30) * 10 + (value[9] – 0x30)); value_4 = ((value[10] – 0x30) * 10 + (value[11] – 0x30)); value_5 = ((value[12] – 0x30) * 10 + (value[13] – 0x30));

Can u please explain the above code?

Hi, The input data from arduino to ESP8266 is received as stream of individual number, here we are grouping the numbers of a sensor using array, so that a sensor data is combined correctly before sending it via internet. For Example, LDR data is sent to ESP8266 as 1 0 0 for 100%. The above block of code combines individual digits to 100 before sending to cloud. The received individual digits by ESP8266 will be their ASCII values, so to convert them to proper integer (before combining) we are subtracting the received individual data with 0x30 hex value. Regards

Thanks a lot:-) Can u please say which value corresponds to which sensor… And how is array length 15?

Hi, Value 1 & 2 are DHT11, Value 3 is BMP180, Value 4 is LDR, Value 5 is MQ-135. Regards

Hello, Could anyone please tell me what is the programming language used for programming here? Thankyou

C language.

Thankyou so much for you’re previous reply. I had another doubt like how the power supply given to the entire circuit?

Hi, The circuit requires 3.3V and 5V, in our circuit setup we used a power supply that accepts 9V in and 3.3V & 5V out. Regards

I am getting DHT 11 SENSOR ERROR others are working what may be the issue. Sometimes it shows the temperature and Humidity but majority of the time it shows as DHT 11 SENSOR ERROR

Hi, There must be loose connections on one or more wires of the sensor.

I am using Nodemcu instead of ESP8266 is there any changes in the code I need to make. Please Share. I am getting output in LCD the problem is I am not getting serial output from Arduino and Node MCU as well as thingspeak. Please help.

Hi, We need to make the project from starch if we want to use NodeMCU.

Hi, You can use any plastic junk box as enclosure for the project and make some vent hole so that there will be proper air circulation for the sensors. Regards

Please check your VCC and GND connections. Check DHT11 sensor out cable connection.

Can we add gsm module in this project.

Hi, Yes you can, also we need to do some additional programming depending your requirements.

Hi. Thanks for the code and setup. But when uploading my code to esp8266 board, I am recieving following error message: esptool.FatalError: Failed to connect to ESP8266: Timed out waiting for packet header

Can you please tell me its meaning and how to solve it?

Hi, Are you using the illustrated programmer kit? If so you need to short the two terminals as shown in one of the images. Usually, it takes only one attempt to program the ESP8266. Regards

What are the advantages over other projects of the same theme?

Hi, This circuit is well tested one and we have integrated a lot of relevant sensors. Regards

Thingspeak shows only zero values

Initially it will show zeros just for one cycle then, it will update actual values. If you can see values on your LCD check Tx and Rx connections between Arduino and ESP8266 for Tx and Rx. Don’t alter any delay in the code.

If arduino nano is used, does the programming code change?

Yes, you can use arduino nano.

1.Sir, after how much time it will show the data, meaning after how long we can see the weather.

2. Sir how we check the practical data with actual data.

Hi, The data will appear after 1 to 2 mins on Thingspeak, initially it will update zeros and then sensor data starts updating. I did not understand your 2nd question. Regards

Hey buddy it’s showing dht11 sensor error

Hi, Please find its correct Vcc, GND and output Pin. These are differs from manufacture to manufacture.

Sir, can we see the results in mobile?

You you can, but still you need to provide 3.3V from a regulator.

I see, can you explain the part of uploading the code to arduino cuz I got confused between uploading the esp8266 code first and arduino code later? Thanks for the reply btw 🙂

Hi, You need to remove the microcontroller from the arduino board so that ESP8266 can be programmed, later you can reinstall the microcontroller to the board and upload the code designated to arduino. You can also upload the code for arduino first, but to make things easy for newbies I mention that.

I see, thanks again for the help 🙂

Can I get the ppt of this project? Because it will use for my study to do my project.kindly send me sir.

Sorry, we did not document a PPT for this project.

I need help, already done uploading the code and everything but the lcd just flashing on and off without displaying anything and in thingspeak nothing showing up 🙁

You wiring to LCD is not proper and also check the voltage that is going to LCD.

Sir, I’m getting dht11 error on lcd and I didn’t get anything in thingspeak. I have checked my wiring and replaced them with new components but the results stays the same

Hi, Your issue with DT11 is pin configuration of the sensor, connect the sensor properly, its +Ve, GND and output. Even if any one of the wire is mismatched you will error. Regards

Configure the pin as digital input, create a new function for the rain sensor, put your values to send_data() function. You need to understand the code before you can start changes in your project. Regards

The ESP8266 is sending all values as 0. I have checked the RX and TX wires. They are connected properly.

Any modification from your side done in the code? only a few time it should update zero at max after that it should update the values.

i got dht 11 sensor error, my all wiring is totally ok, please help about the error

Hi, either you sensor is damaged or still your wiring to DHT11 is incorrect.

I am getting nan at the output terminal:

Hi, The serial terminal was not configured in the first place in this project 🙂

IoT Based Weather Monitoring System For Micro-Climate Forecasting

Jan 1, 2022 | Blog , IoT Based Weather Monitoring System

IoT Based Weather Monitoring System For Micro-Climate Forecasting

Forecasting the weather has come a long way from where it once used to be. Not too long ago, the only way to find out about the day’s weather was through local news channels, radio stations or through aviation weather services. Now, it’s just one click away—all you have to do is check your smartphone.

Environmental monitoring has become incredibly important, given people’s need to be aware of the latest weather conditions wherever they go but more importantly, whatever their profession. Technology is evolving at a dynamic rate, and weather stations need to adapt in order to keep pace with consumer and commercial demand for accuracy. And one of the most important factors that must be considered are microclimates.

What are microclimates?

Weather is not always forecast accurately. One of the biggest drawbacks of the current weather forecasting system is that it is done on a grid. To produce day-to-day forecasts, global model grid lengths range between 9 and 13 km in the smallest sections of the grid all the way up to hundreds of kilometers, leading to inaccurate and inconsistent reports.

These grid systems can not consider microclimates , which are much smaller pockets of land with distinct features that affect temperature, precipitation, and wind.

Some common microclimates include:

  • High-elevation areas
  • Coastal regions
  • Large forests
  • Urban landscapes

To improve weather forecasts in a very specific location, it becomes important to understand and identify microclimate conditions. Whether it’s the topography or construction elements affecting different weather factors, accurately collecting data is essential for microclimates around the world.

So how does a microclimate form? It depends on different topographical features that would affect normal climate and weather patterns. For example, the contrast in topographies can affect airflow, ambient temperature, and cloud formation. The particular soil composition of land can have an effect on its rate of evaporation. Heavy vegetation on a specific area can affect airflow as well as moisture levels; this can be natural or manmade.

Microclimates aren’t limited to differences in nature; unnatural additions to a particular landscape can also create them. Urban centers generate high amounts of heat and smog, which can affect low- and high-level winds. Several acres of parkland in the middle of a city can cause multiple microclimates to emerge in a very small geographic area as well. The same principles apply to agriculture as well; differences in crops, irrigation practices, etc. can affect the microclimate as well.

Due to the very specific characteristics of locations with microclimates, it becomes difficult for a traditional grid-based monitoring system to consider different environmental factors. For example, certain variances can have a significant impact on predicting the path of a hurricane or a snowstorm. For someone who lives in or near such microclimates, the forecast as seen on TV may not be accurate.

In addition, conventional grid-based weather monitoring systems are bulky, expensive, and require constant surveillance . Data is transferred manually, which increases the margin for error and runs up expenses.

Here’s where an IoT-based weather monitoring system steps in.

What is the Internet of Things (IoT)?

So what exactly is the “Internet of Things” (IoT)? Simply put, it is a technology that looks to connect all kinds of devices and sensors to share the data obtained from various locations. Today, IoT devices are used across all industries, processing and analyzing data to coordinate traffic signaling, ensure industrial safety, monitor medical applications, or even regulate the temperature inside a house.

The Internet of Things offers a wide range of connected devices with different protocols in order to achieve complete machine-to-machine interaction. It is viewed as one of the biggest innovations in the data industry. This system connects everything to the internet, with the aim of exchanging data to trigger corresponding actions when needed.

IoT envisions a near-future where regular day-to-day objects will be fitted with microcontrollers and convention stacks that will make the devices ready to talk to each other. It looks to recognize, find, follow, observe, and oversee data across many different gadgets. The end goal of IoT is to make the internet more immersive and helpful.

The technology is an advanced solution for connecting different devices to the internet (in this case, the factors affecting the micro-climate of a region) and connecting them within a network. With the use of sensors and automotive electronic equipment, an advanced system can be developed to keep track of the many different characteristics of the climate, such as temperature, humidity, wind speed and direction, rainfall, and more. The system can then analyze all collated data and generate accurate microclimate forecasts that can be displayed in real-time on a digital screen ( this is part of what we are doing for agriculture here at Benchmark Labs ).

An IoT-based weather monitoring system connected to data centers could also keep track of past information, either on an hourly or a daily basis. The sensor data can be analyzed and plotted in graphs and statistics to further improve forecasting.

What does an IoT-based weather monitoring system entail?

IoT-based weather monitoring technology has been growing very quickly, and it has already bypassed the features and functionalities of conventional systems in many ways. Having been applied in the field of remote monitoring and advanced analytics, the technology is revolutionizing different ventures while offering a range of benefits.

Innovations in weather monitoring have focused on controlling and monitoring different weather conditions. IoT devices help measure the physical parameters of a certain location and upload them in real-time to cloud storage, where the data can be analyzed immediately.

These systems make climate monitoring in difficult geographical terrains possible. The manpower required for accurate microclimate forecasts is significantly reduced, and there is no longer any need to physically go into inhospitable environments just to get accurate measurements. Sensor devices placed in particular locations can do all the work to detect current climate details, such as rainfall, wind speed, humidity, soil moisture, CO2 levels, and other data needed for forecasting.

Going a step further, when one connects the weather station to the internet, IoT can be used much more extensively in predicting and disseminating accurate weather data in a particular location. This information can then be made available anywhere in the world.

Wireless weather monitoring significantly impacts businesses across different industries. Data received from sensors can be collected by microcontrollers and dispatched where it is needed. When leveraging IoT technology, other systems such as home automation, wireless sensor networks, and control systems can work smarter and more efficiently.

Accurate and timely microclimate forecasting using IoT plays a very important role in the field of agriculture, as it can provide farmers and landowners specific weather information that will dictate their daily operations. This technology can also make it possible to safely monitor extreme weather conditions in inhospitable environments.

Here are some of the advantages of using an IoT-based weather monitoring system when it comes to microclimate forecasting:

  • The process is fully automated
  • Does not require human attention
  • Prior alerts of accurate weather conditions
  • Low cost and efforts in the system
  • High accuracy
  • Self-protection
  • A smart way to monitor the environment
  • Efficient & time-saving

What’s next?

Understanding the conditions in a microclimate can help meteorologists and locals alike receive an accurate and specific weather forecast. Given the many factors that affect temperature, precipitation, and wind, accurate data collection and real-time analysis are more critical than ever.

IoT combined with the traditional grid forecast provides an efficient and low-cost solution for continuous monitoring of the environment. These sensor devices and robust systems can easily collect data and create a more accurate picture of a microclimate.
