Effective Weather Monitoring System using MQTT Protocol

The primary purpose of weather stations is to investigate the weather and environment. A weather monitoring system is necessary to gather data for weather forecasts by measuring atmospheric conditions with tools and equipment. This weather station essentially detects the occurrence of rain, humidity, and temperature. The prototype has a wide variety of sensors that can be used to precisely measure all the aforementioned parameters. It is used to keep track of and warn us about the temperature or humidity of a specific location, even a room. It can keep track of when it rains. This study utilizes an embedded Wi-Fi module-equipped microcontroller (ESP32) in this application. The temperature as well as humidity sensor (DHT11), the raindrop module, and the controller are all directly coupled to these three sensors.
