It consists of Arduino Mega 2560 micro controller unit, soil moisture sensor, raindrop sensor, RF wireless module relay unit, and solenoid valve. This system monitors the environment weather and makes a decision about when the solenoid valve should be open and motor goes to ON state. Data is transfered from the sensor to the MCU through wired communication. Motor and solenoid control signals will be transmitted through the wireless module. The MCU periodically checks the weather and soil conditions by the soil moisture sensor and rain drop sensor.
