1. Overview
The P916H is a pyroelectric infrared sensor that integrates a digital intelligent control circuit and a human body detection sensitive element in an electromagnetic shielding cover. The human body sensing sensor couples the sensed body motion signal to the digital smart integrated circuit chip through a very high impedance differential input circuit. The digital smart integrated circuit converts the signal into a 15-bit ADC digital signal when the PIR signal exceeds the selected digital valve. The value will have a timed REL level output.
2..the characteristics Digital signal processing, low voltage, low power consumption, and work instantly after startup. Two-way differential very high impedance sensor input Second-order Butterworth bandpass filter with built-in infrared sensor to shield input interference at other frequencies Sensitivity, timing time, illumination sensor Schmitt REL output. 3.

8. Precautions
When there are stains on the window, it will affect the detection performance, so please pay attention.
The lens is made of a weak material (polyethylene). When a load or impact is applied to the lens, malfunction and performance deterioration may occur due to deformation and damage, so avoid the above.
Failure to apply static electricity of ±200V or more may cause damage. Therefore, please pay attention to the operation, avoid touching the terminal directly by hand.
When soldering a wire, solder the soldering iron at a temperature of 350 ° C or less and soldering within 3 seconds. When soldering through a solder bath, performance may deteriorate, so avoid it.
Please avoid cleaning the sensor. Otherwise, the cleaning liquid may intrude into the inside of the lens, which may cause deterioration in performance.
When using the cable wiring, it is recommended to use shielded wires to minimize the influence of interference.
