Abstract: The topic of this essay is how to irrigate agricultural systems using solar power. This system uses moisture sensors to determine the soil's moisture content, and a controller will control the water pump's ON/OFF status using solenoid valves in accordance with that information. This project uses renewable energy, specifically solar energy, rather than non-renewable sources. A smart phone is used by an Arduino-based irrigation system to determine the state of the field. Moisture sensors provide data to Arduino as the soil's moisture content. The Arduino will activate the water pump by comparing this input value to a threshold value. the user's use of the GSM module to receive the motor's action. To supply water to the field in accordance with, the solenoid valve is used.

Keywords: Water pump, solenoid valve, solar panel, GSM modem, moisture sensor, and motor driver.
