Anti-theft Digital Intelligent Human Body Movement Pyroelectric Infrared Sensor P916 PIR
Description Of The P916 PIR Sensor
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.

Precautions Of The P916 PIR Sensor
●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.
