    Abstract: An irrigation system for controlling a number of control valves (104) is disclosed. The valves (104) control the flow of water in a corresponding branch pipe (102) leading from a common supply pipe (101). The system uses wireless transmission of control signals to operate a control unit (115) which operates the corresponding control valve (104) from a corresponding power generator (107).
