An Automated System for Irrigation and Frost Protection

This paper describes details of the design and instrumentation of an automated system for irrigation and frost protection, comprising a soil moisture sensor and a temperature sensor, two water tanks wherein one of them is connected to a heating system, two water level sensors; one in each tank, a pump with automated switching system, two solenoid valves between the pump and each of the tanks, a control unit, an array of sprinklers and at least one solenoid valve between the pump and the sprinklers. The system is also provided with means for emitting acoustical and visual alarms.
