BT31W PIR Sensor Motion Sensor Energy Saving Motion Detector Wall Mounted

Awesome product. Works perfectly well Spend some time in the instruction manual to understand the setting Same like the sensors seen in Germany Keep up the Awesome work guys

An impressive PIR (Passive Infrared) motion sensor. Has a very good response time. Triggers the sensor when a heat emitting body moves in its detection field (works fine for 160+ degree coverage & up to 10-11 meters distance). A problem which I noticed was that minor motions, even human, are ignored and if the device is connected to a light in a room you will have to make serious motions between the set time period or else the sensor won't trigger. So if you are powering a light source with this sensor in a computer room you will have to wave your hand or make some sort of motion within the set time delay or else the sensor will trigger off.

Achcha hai

Sensor has not a wide angle. It works only when someone is moving infront of this. The wide angle is less than 30 degrees. Sensor doesn't work if kept over 4 meters range. I have installed it in my gallery of 10 meters but it only works when you are at a distance of around 4 metres or less. Motion sensing is slow. If you run infront of it, it doesn't work. The lights are on after a delay of 2 seconds.

Works as expected and detects motion, good quality and easy to install.

Stoped working after 10 days Not recommended

Nice looking nice work and best quality

Good working

So far it is working fine as expected
