Product details
1、 Product Overview
RES812 is a pyroelectric infrared sensor that integrates digital intelligent control circuits and human detection sensitive elements into an electromagnetic shielding cover. The human detection sensitive element couples the sensed human movement signal to the digital intelligent integrated circuit chip through a very high impedance differential input circuit. The digital intelligent integrated circuit converts the signal into an ADC digital signal, and when the PIR signal exceeds the selected digital threshold, there will be a timed REL level output. The OEN enable end can enable REL output or automatic control through a light sensor. Sensitivity and time parameters are set through voltage divider resistors. All signal processing is completed on the chip.
