About this project

The project is the development of a prototype, of an automated irrigation system, taking temperature and humidity as variables, it is developed with a DHT22 sensor, arduino uno board, board with mosfet transistor, lcd 16 * 2, motor. The device works as follows. The DHT22 device starts sensing, sends the data to the arduino, which the arduino transmits the reading to the lcd 16 * 2, with a conditional variable declared in the arduino programming, if the sensor sends a temperature data greater than 33 degrees Celsius, the arduino will activate a digital output to the mosfet circuit, activating the ignition of the motor pump, when sensing, a temperature below 30 degrees, the digital output will deactivate and turn off the pumping equipment, starting another sensing cycle again.
