433MHz Wireless PIR Motion Detector Unit

The 433MHz Wireless PIR Motion Detector Unit adds reliable perimeter and room-entry security to compatible 433MHz home and commercial alarm systems. Utilizing passive infrared (PIR) sensing technology and wireless radio frequency transmission, this compact sensor detects human body heat and movement, instantly triggering alarm host panels without requiring hardwired installation. Hardwiring motion sensors through interior walls and ceilings requires invasive drilling and long cable runs, making installations costly and inflexible. Operating on the universal 433MHz wireless frequency with battery power, this PIR detector mounts quickly on walls or in corners—delivering instant motion-triggered alerts to your central alarm control unit with zero wiring hassle. Key Features 433MHz wireless RF transmission → Wirelessly connects with compatible 433MHz alarm host panels, sirens, and smart home gateways over long transmission distances. Passive Infrared (PIR) technology → Detects infrared heat signatures emitted by moving human bodies for accurate intruder detection. Wide-angle coverage → Delivers expansive coverage angles (typically up to 110° horizontally and 9–12 meters range) to secure entire rooms. Low power consumption & battery operation → Powered by long-lasting batteries with built-in low power consumption circuits for extended operational lifespan. Anti-tamper & false alarm reduction → Features integrated temperature compensation and digital signal processing to reduce false triggers caused by draft currents or minor temperature shifts.
