Overview

BX604 is a pyroelectric infrared sensor that integrates a digital intelligent control circuit and a human detection sensor in an electromagnetic shielding housing. The human body detection sensor couples the sensed human movement signal to the digital intelligent integrated circuit chip through a very high impedance differential input circuit, which converts the signal into an ADC digital signal, and when the PIR signal exceeds the selected digital threshold, there is a timed REL level output. The OEN enable allows the REL output to be automatically controlled via a light sensor. The sensitivity and time parameters are set by a voltage divider resistor. All signal processing is done on the chip.


Feature

Digital signal processing

★ Low voltage,Low power consumption ,Short warm-up time

★ High power supply rejection ratio, anti-radio frequency 

    interference(mobile phone,WiFi,etc.)

★ A second-order Butterworth bandpass filter with built-in

    infrared sensor to shield input interference at other 

    frequencies

★ Sensitivity,Ontime,and light sensor Schmitt REL output

★ Ontime adjustable

★ Good stability and effective suppression of repeated

    malfunctions

★ Simple application circuit
