AS-920 infrared sensor is based on the infrared spectrum of the human body for work. When the human body is active within its acceptance range, the sensor receives its heat source signal, and input to the microprocessor after amplification, the microprocessor continuously samples the infrared signal. After calculation, the microprocessor output signal to control the sensor alarm port.
This product is widely used for banks, warehouses, homes and other places.
