BX604

BX604 Product Introduction

BX604 is a pyroelectric infrared sensor that integrates a digital intelligent control circuit and a human detection sensor within an electromagnetic shielding housing. The human body detection sensor couples the sensed human movement signal to the digital intelligent integrated circuit chip via a very high-impedance differential input circuit, where the signal is converted into an ADC digital signal. When the PIR signal exceeds the selected digital threshold, a timed REL level output is triggered. The OEN enable function allows the REL output to be automatically controlled through a light sensor. Sensitivity and time parameters are configured using a voltage divider resistor. All signal processing is performed on-chip.
