We are living in a technology-based society where we have lots of innovative ideas day by day. These new innovations in IoT communications-based projects, strive constantly to share and gather insight on the latest trends in the industrial IoT landscape. Here we focus on the IoT Weather Reporting System that can perform weather parameter reporting over the internet.

Nowadays Weather forecasting has become unpredictable to be exact due to the drastic climate changes over the weather. Due to this, the Weather Reporting System is widely used to monitor the continuously changing climatic and weather conditions over controlled areas like houses, industry, agriculture, etc. in real-time monitoring.

Basically, Satellite weather forecasting provides the condition of the present climate which does not give the exact condition of the particular place. As this climate offers great potential for energy savings in various sectors, it is quite important to have accurate weather data in the exact location.

This IoT-based weather reporting system is the best solution to facilitate the reporting of weather parameters over the Internet. This is one of the best IoT projects where the system is embedded with temperature, humidity, and rain sensors that can monitor the weather conditions and provide live reports of weather statistics.

What is Weather Reporting System?

This smart weather reporting system functions over the internet. Our proposed IoT-based system reports the weather parameter over the internet. It allows people to directly check the weather stats online without the need for a weather forecasting agency. This Weather Reporting System makes use of temperature, humidity as well as rain sensor to monitor the weather and provide live reporting of the weather statistics. The system constantly monitors temperature using a temperature sensor, humidity using a humidity sensor, and also for rain. The system constantly transmits this data to the microcontroller, which now processes this data and keeps on transmitting it to the online web server over a wifi connection. This data is life updated to be viewed on the online server system. Also, the system allows users to set alerts for particular instances, the system provides alerts to users if the weather parameters cross those values. Thus the IoT based weather reporting system provides an efficient internet-based weather reporting system for users.

How Does the Weather Reporting System Work?

In this IOT based weather monitoring system project, Arduino Uno measures four weather parameters using four respective sensors. These sensors are a temperature sensor, humidity sensor, moisture sensor, and rain level sensor. These four sensors are directly connected to Arduino Uno. Arduino Uno has an inbuilt Analog to digital converter. Arduino calculates and displays these weather parameters on the LCD display. Then it sends these parameters to the Internet using IoT techniques. The process of sending data to the internet using Wi-Fi is repeated after constant time intervals. Then the user needs to visit a particular website to view this weather data. The project connects and stores the data on a web server. Hence user gets Live reporting of weather conditions. Internet connectivity or Internet connection with Wi-Fi is compulsory in this IoT based weather monitoring reporting system project

Arduino Uno: Arduino Uno is an open-source based on the Microchip ATmega328P developed by Arduino. cc. The current version of Arduino Uno comes with a USB interface, 14 digital I/O pins, 6 analog pins, an ICSP header, 16 MHz ceramic resonators, a power jack, and a reset button. And an Atmega328 microcontroller is used to connect with external electronics circuits. Out of 14 I/O ports, 6 pins were used for PWM output. Each pin operates at a voltage of 5V providing a maximum of 50mA. It also supports serial communication using Tx and Rx pins.

Soil Moisture Sensor: Soil moisture sensors measure the contents in soil. Since the direct gravimetric measurement of free soil moisture requires removing, drying, and weighting of a sample, soil moisture sensors measure the volumetric water content indirectly by using some other property of the soil, such as electrical resistance, dielectric constant, or interaction with neutrons, as a proxy for the moisture content.

WiFi Module: The Arduino Uno WiFi is an Arduino Uno with an integrated WiFi module. The board is based on the ATmega328P with an ESP8266 WiFi Module integrated. The ESP8266 WiFi Module is a self-contained SoC with an integrated TCP/IP protocol stack that can give access to your WiFi network (or the device can act as an access point). One useful feature of Uno WiFi is support for OTA (over-the-air) programming, either for the transfer of Arduino sketches or WiFi firmware.

LCD Display: A Liquid Crystal Display commonly abbreviated as LCD is basically a display unit built using Liquid Crystal technology. When we build real-life/real-world electronics-based projects, we need a medium/device to display output values and messages.

  • The weather forecasting plays very important role in the field of agriculture.
  • It is also helpful at places like volcano and rain forests.
  • It is quite difficult for a human being to stay for longer time at such places. 
  • Prior alert to the weather conditions 


  • Can implement a few more sensors and connect it to the satellite as a global feature of this system.
  • Adding  more sensor  to monitor  other environmental parameters such as CO2,Pressure and Oxigen Sensor
  • In aircraft, navigation and military there is a great scope of this real-time system.
  • It  can  also be  implemented  in hospitals  or  medical institutes for the research & study in “Effect of Weather on Health and Diseases”, hence to provide better precaution alerts


In a conclusion, the objective of this project is to build a system that can monitor weather parameters by the wireless system and IoT. The Sensor station and Weather station will be communicated by hotspot Wi-Fi and it is limited in areas covered but still better in communication via wireless. The value that has been recorded that the weather at a particular place has different conditions from the exact condition with the accuracy of the weather reporting system and forecast system data has been compared. Moreover, it says that the weather reporting system is more accurate than the forecast system. This is said to be one of the best IoT projects where the system is embedded with temperature, humidity, and rain sensors that can monitor the weather conditions and provide live reports of weather statistics. By using sensor devices in the environment, we can bring the environment into real life. This model can be expanded to monitor the developing cities and industrial zones for pollution monitoring.
