A Robust Irrigation System with a Flow Sensor

An autonomous precision irrigation is drawing its attraction as it can reduce labor and water, and improve productivity in agriculture. This paper presents the design of a robust pump control system that can irrigate to a designated area with a fixed amount of water or run times. The system is able to turn off the pump in exceptional situations such as the absence of water. We experiment the implemented system with a drip-irrigated plant pot, showing the designed pump control algorithm works correctly.
