    1. Overview
    The P916 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.

    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.
