This paper presents a low cost automated solar water pumping system for irrigation in developing countries. The programmed sensor module detects the temperature, humidity, soil moisture level and sends the information to ESP32 microcontroller. A water level sensor also observes the water level and sends the data to the microcontroller unit. Based on the information and boundary conditions, the micro controller decides either to start or to stop the pump motor. This paper also describes how to decide soil moisture limits for a particular type of soil. The ESP32 microcontroller also sends results to the web server so that the user can see that. The user can operate the irrigation system far from the field by a simple click on a cellphone. A manual ON/OFF system is also incorporated into the proposed design.
