IoT based Monitoring and Controlling of Environmental Parameter for Implementing Intelligent Irrigation System

The Solar Powered Drip Irrigation Method was designed to reduce agricultural water consumption. The proposed module utilizes a microcontroller and several sensors such as soil moisture sensors put in root system belts, temperature sensors, and ultrasonic sensors positioned at the tank's roof. The water volume in the tank is maintained using the on and off operation of the pump. Then the moisture content and temperature are regulated by opening and closing of the solenoid valve. A Wi-Fi module is connected to the control unit that processes sensor data, initiates actuators, and broadcasts data over the internet, allowing the user to watch the farm in real-time from whatever distant area. The programmed code was designed depending on the soil moisture, humidity, and temperature values and is programmed into the central controller to regulate the amount of water delivered to the area for irrigation and the pump to fill the water in the tank. Renewable solar power the entire system. The sensing unit, actuating unit, and the central control unit are wired together, and the control unit communicates with the app through a wireless link. The primary goal of the research is to reduce the farmer's manual intervention, which saves money and resources.
