Design of Trickle Irrigation Control Unit Using PSoC

Prolonged periods of dry climatic conditions due to fluctuation in annual precipitation, may appreciably reduce the yield of the cultivation. The expenses in establishing many of these crops and their relative intolerance to drought make an effective irrigation system a necessity for profitable enterprises. The fact that majority of the crops are planted in widely spaced rows and require soil water content to be maintained at relatively high levels, makes them well adapted to trickle irrigation. This paper proposes a System level design of a PSoC based control unit for trickle irrigation system.
