Blackt Electrotech: (BT31M1) Microwave/Radar Motion Sensor Occupancy Motion Detector Small Sq Shape 18 Months warrenty (2)

have been using these microwave sensors for about 6 months now and they are very useful and works superbly. They can be adjusted to your needs in terms of sensitivity, time delay, and range. I have 3 such sensors at home conveniently placed where not frequent movement happens.. and kids sometimes forget to switch off lights.. this is a major power saver..

Product recd today and tested working ok but while ceiling fan is on then unit not switching of the light due to fan blade movement no other issues.

As there were several robberies in the compound decided to install BlackT motion sensor with a light and buzzer alarm. Over the past few weeks it has been working very well switching on when any one moves infront of it at night. Saved a lot as watch man not needed who any way goes to sleep anyway

No good

Nice and small sensor. Can be installed without any tools. I have sticked it to the roof light using hot glue. Keeps sensing activity and light does not turn off untill the room is empty. The sensitivity setting is another convenience feature. You can limit the radius of movement sensing.Very happy with the buy.

This motion sensor doesn't work properly.It is not useful.It does not serve the purpose.Do not buy.

I love the operation of the product. It works only when it is dark if you set the LUX sensor appropriately. It turns on immediately when I open the door.However, the timer isn't accurate. Sometimes, it switches off at the set time, and a few other times, it takes a few seconds longer. The device looks a little cheap. The company definitely need an English-speaking employee to correct their English in their manual/instruction.Overall, it's a fantastic product. I will order more of them for all my lights and recommend it to all prospective buyers.

Best performance,It gives good results in all matters.
