Wireless PIR motion sensor

A PIR sensor, or passive infrared sensor, responds to movement in the detection area of ​​its infrared sensor and is only usable indoors.

When a PIR sensor detects movement in its detection area, the sensor sends an alarm signal to the security device. The sensor signals movement in the detection area with a red flashing LED indicator. After motion is detected, the sensor has a rest period of approximately 25 seconds to extend the battery life. The sensor is powered by one CR2450 battery.
