BX304 Pyroelectric Infrared Sensor
BX304 pyroelectric infrared sensoris a type of intelligent PIR sensor which integrates digital circuit and sensitive element in a hermetically sealed package. It interference directlly with up two conventionao PIR sensors via a high impedance differential input. The PIR signal is converted to a digital value on chip. All signal processing is performed digitally.
