PIR Sensor P916H Digital Control Human Detection 2.7-3.3V Low Power 15μA Current
The P916H is a RoHS-compliant pyroelectric infrared sensor that integrates a digital intelligent control circuit with a human body detection sensitive element within an electromagnetic shielding cover. This advanced sensor couples detected body motion signals through a high-impedance differential input circuit to a digital smart integrated circuit chip.
- Digital signal processing with 15-bit ADC conversion
- Power regulation for enhanced energy savings
- Dual differential high-impedance sensor input
- Built-in second-order Butterworth band-pass filter
- High power supply rejection ratio and RF interference resistance
- LED sensor dynamic output port
- Low voltage operation (2.7-3.3V) with minimal power consumption
- Instant operation after startup
Digital frames, sensor lighting, TV/refrigerator/air conditioning controls, web video cameras, USB alarms, PIR motion detection, intrusion detection, occupancy detection, interior lighting systems, corridor lighting, building automation, private alarms, LAN monitoring, and automotive theft prevention systems.

• Keep sensor window clean to maintain optimal detection performance
• Avoid mechanical stress on the polyethylene lens to prevent deformation
• Handle with care to prevent electrostatic discharge damage (±200V limit)
• Use soldering temperatures below 350°C with maximum 3-second duration
• Avoid cleaning liquids that may penetrate the lens housing
• Recommended use of shielded wiring to minimize interference
