Claim Text:
1. A temperature activated shower controller, comprising: a temperature sensor having a thermistor device and being adapted to measure the temperature of water supplied to a shower head at at least two consecutive points in time such that the temperature sensor determines a rate of change of temperature between the points in time; a valve adapted to allow or reduce the flow of water to the shower head; and a microprocessor responsive to a signal produced by the temperature sensor when a predetermined rate of change of temperature is detected, the microprocessor further adapted to control the operation of the valve according to a pre-programmed shower duration, wherein the temperature activated shower controller is activated in response to detection of the pre-determined rate of change of temperature by the temperature sensor, the predetermined rate of change comprising a rate of change of temperature of about 0.5° C. over two consecutive 8 second intervals, and wherein when activated and within a given period of time, and if a shower duration has not been selected, the microprocessor defaults to a pre-set shower duration after which duration the valve moves to the closed position to reduce the flow of water supply to the shower head.
