摘要： A low power consumption system for monitoring time of use of appliance incorporates a controller and a temperature sensor that is activated by the controller at intervals of X minutes to determine the temperature of the sensor. The sensed temperature is then compared with a threshold temperature and a counter is turned ON to accumulate time if the sensed temperature is at the desired level or turned OFF when the sensed temperature is not in the desired range. The counter remains in its ON or OFF position until the sensed temperature causes the counter to shift to the opposite position to the one it is in at that time. The counter receives oscillations from the oscillator which is continuously operating and only counts those oscillations when the counter is set in the ON position.
