Abstract

PURPOSE:To automatically perform a ventilating operation for an appropriate time interval by causing an infrared ray sensor to detect and output a voltage signal proportionate to the amount of change in the entering infrared ray energy, said infrared ray-dependent signal being evaluated by a comparator, and causing a delay timer to be operated depending the evaluation result to actuate an actuating means on the delay timer output signal. CONSTITUTION:An infrared ray sensor 1 attached to a ventilating fan performs a derivative control action in response to the entering infrared ray energy, and outputs voltage signal according to the appearance or diappearance of a person within its detection field or the movement of a person within the detection field. The amplified signal is inputted to a comparator 3 which compares the signal output level with the detection sensitivity reference value given by a detection sensitivity regulator 4, and, if the signal is determined to have derived from a person, a delay timer 5 is initialized and starts the ON operation for a certain time interval. While the delay timer 5 is ON, an actuating means 6 is actuated to operate a ventilating fan 7. When the time limit is up and the delay timer 5 becomes OFF, the ventilating fan 7 is stopped unit a signal derived from a person is inputted.
