S918-H is a pyroelectric infrared sensor that integrates a digital intelligent control circuit and a human detection sensitive element in an electromagnetic shielding cover. The human detection sensitivity element couples the sensed human movement signal to the digital intelligent integrated circuit chip through the very high impedance differential input circuit. The digital intelligent integrated circuit converts the signal into a 15-bit ADC digital signal when the PIR signal exceeds the selected digital valve. When there is a value, there will be a regular REL level output. The OEN enable enables the REL output or automatic control through the light sensor. Sensitivity and time parameters are set by resistors and correspond to corresponding values, and their voltage is converted into a digital threshold with 7-bit resolution. All signal processing is done on the chip.
