BS612 Product Introduction

BS612 is a pyroelectric infrared sensor that integrates a digital
intelligent control circuit and a human body detection sensitive element
within an electromagnetic shielding enclosure. The human detection
sensor couples the sensed human motion signal to the digital intelligent
integrated circuit chip via a very high-impedance differential input
circuit. The digital intelligent integrated circuit then converts this
signal into an ADC digital signal. When the PIR signal exceeds the
preset digital threshold, a timed REL-level output is triggered. The OEN
enable terminal facilitates either REL output or automatic control via a
light sensor. Sensitivity and timing parameters are configured using
voltage divider resistors. All signal processing is performed on-chip.
