Abstract

PURPOSE:To utilize information on two values that an infrared sensor by composing the comparator of two operational amplifiers and obtaining two comparison outputs according to two comparison voltage inputs. CONSTITUTION:The output of the infrared sensor 1 is inputted to the operational amplifies 3 and 4 through an amplifier 2. The amplifiers 3 and 4 are applied with the comparison voltages VH and VL and send out outputs 1 and 2. Consequently, the comparison output when a human body enters the detection range of the infrared sensor is obtained from the amplifier 3 and the comparison output when the human body exiting from the detection range is obtained from the amplifier 4. The two-value information that the infrared sensor has is therefore utilized effectively.
