PIR sensor detects a human being moving around within approximately 10m from the sensor. This is an average value, as the actual detection range is between 5m and 12m.PIR are fundamentally made of a pyro electric sensor, which can detect levels of infrared radiation.
Wall Mount PIR Motion sensor is a unique indoor or outdoor sensor used for lighting and security alarm system for your home or business. At night, the built-in infrared (PIR) motion sensor turns on the Floodlight when it detects motion in its detection field. The built-in light sensor can be activated during the day in order to save electricity. An adjustable timer makes you able to select how long the Floodlight needs to stay on after activation.
You can install Light or Alarm or both at output of motion sensor as load
1) TIME: TIME knob controls how long the Floodlight will stay on after the last motion has been detected.
The minimum TIME is 10sec., the maximum TIME is 7min.
2) LUX: LUX knob determines at what light level the Floodlight will start working, so it actually controls the built-in light sensor
