ELECTRIC HOME APPLIANCES Abstract of the Disclosure An electric home appliance which is automatically controllable with use of a sensor such as temperature sensor or humidity sensor. Variations in terms of analogue quantities given by the sensor are converted to variations in the number of pulses by an oscillator connected to the sensor and comprising an astable multi-vibrator or the like. The number of pulses is counted by a counter, the gating time of which is determined for example by divided frequency of a commercial power supply. The control system is inexpensive to make and has high reliability.
