KERUI 433MHz Wireless Infrared Detector Indoor PIR Motion Sensor

Features:
This security motion detector uses passive infrared technology, ensuring maximum security at your home or business. It is used to sense movement of people. Detection distance is 4-8 meters, and detection angle is 110 degrees.
Adopts digital dual-core fuzzy logic infrared control and processing technology and intelligent analysis algorithm, which can effectively distinguish interference signals and human movement signals and prevent false positives.
When the motion detector is triggered, the LED indicator will flash once and send signal to the alarm host. You will receive the notification at the first time.
Low power circuit design, more power-saving. When the battery voltage is lower than 2.4V, the detector indicator flashes 3 times and sends low battery signal to the alarm host.
Suitable for indoor use. Widely applicable to family residential area, villas, factories, shopping malls, warehouses, office buildings and other places.
Note:
1. The sensor must work with alarm system, it can not work independently.
2. Avoid installing in windows, air conditioners, refrigerators, lamps and other places where the temperature will change rapidly and the air flow will be fast.
