Title: Soil Irrigation Controller
IPC: A01G25/16
Filed: 1980-05-08
Abstract: A soil irrigation controller has a soil probe (71) which provides a signal indicative of soil moisture level. An electronic device (80), which may be a computer, monitors the output from the probe (71) and controls a valve (68) to supply irrigation water e.g. by sprinklers (63). The device (80) compares the probe output with a reference and controls irrigation to counteract any difference between the probe output and the reference. If the rate of change of the probe output exceeds a pre-set rate, then the reference is automatically shifted in a predetermined fashion. In one arrangement if the rate of change of probe output indicates increased moisture usage, the reference is shifted to provide increased moisture level. In another arrangement relatively sudden spurious changes in probe output cause the reference to be shifted in the same direction by an equivalent amount. A multichannel controller controls irrigation separately to several growing areas. <IMAGE>
