An Irrigation Control System Based on C8051F and ARM

A system of solar energy water saving irrigation adaptive control system is proposed, composed of the central controller and sensor nodes, based on the soil structure of karst sloping lands and the characteristics such as electricity difficulties. The central controller chip choose S3C2440, sensor node controller chip choose C8051F120. By compare the soil humidity and temperature value received from the sensor nods with the high/low limit value in the database of the central controller, to decide whether open or close the electromagnetic valve. The central controller has the touch screen and operation function, easy to operate. The full system powers with the solar, has sleep mode, automatic/manual switching irrigation modes for managers, historical records query and storage function.
