Abstract

The Internet connectivity of Internet of Things (IoT) devices over the network has drastically reduced the facility usage persistence and connection needed to access data over the network. The Internet of Things (IoT) is widely recognized as a reliable technology that may assist in the development of several industrial sectors. The Internet of Things is utilized in the process of developing a weather monitoring system in this project. The weather has a big effect on human activities like farming, transportation, and many others. So, keeping an eye on the weather can help to keep control over the action. Lack of real-time localized weather data and point rainfall measurements impedes accurate weather monitoring is the the one of problem statement. The need of localized weather data is important to get more accurate in weather monitoring. Insufficient data also lead to accurancy and efficiency in a system. The purpose of this system is to develop an IoT based weather monitoring system that can collect and transmit weather related data using IoT technology. In addition, the objective also to display a real result that enables users to access data from any location. Next, to test the capabilities and functionality of the system when generating the data and display the result to user. A weather station is a capability that can be used for measuring atmospheric conditions such as temperature, humidity, rain, ultraviolet and atmospheric pressure in order generate information for weather forecasts as well as to study the weather and climate. The Nodemcu Microcontroller, the raindrop sensor, DHT11 for temperature and humidity sensor, the BMP180 pressure sensor, and UV sensor to measure ultraviolet intensity have all been utilized in the development of this project. The sensor will establish a connection with the NodeMCU, and the result will be presented in the ThingSpeak and mobile applications. The integration of NodeMCU, DHT11, BMP180, raindrop sensor, and UV sensor has been successfully developed and tested.
