Blackt Electrotech Microwave Radar Sensor Switch - Ceiling Mounted Occupancy Motion Detector for Automatic Lighting Control (Regular Size)

Overall a good product and works good.

First days of use....I've got this after I've used the pir in the garage. Pir sensors detect thermal footprints by living things perfectly but fails with metal objects. So I moved my PIR sensors to my balcony and kitchen. Installed this microwave sensor in the garage. Works fine with great range of detection upto 7 meters. This is much advanced and compact than the PIR.Highly recommended.*After a week.... Seems to work shady, doesn't detect if standing in a perpendicular view to the firing sensor even within 4 meters... Doesn't seem to work 360° ... Only senses in a circular (peripheral) direction for 7 meters. The engineering team must look into this issue. Or else this is totally worth it. I installed the sensors in the garage and balcony... Works okay... Must see if they survive the coming scorching summer & monsoon's humidity.

I bought 2. It's a good product. Very sensitive to movement. Instructions are clear on the product. I had it installed in the toilet for my workers about 2 months ago. It's working perfectly fine till now despite moisture. And yes the light does not effect it when it's directly.in front of it, which is a very important thing for this kind of setup.

This is very useful product. It's work is Accurate. It is helpful in saving electricity. This is a must-have product for everyone's home. Already I have bought Wireless remote control for Fan and Lights From BlackT company. It is working well till now. As the same I think this product also will work well. And Installation process is also very simple. 100% Satisfaction for me. Thank you Blackt. I am Waiting for your Next different Product.

The product built quality is excellent. However, it was very difficult to set the LUX settings. Full dark or full bright is OK. But what I wanted is that when you draw the curtain in a room (even in daytime) to make it sufficiently dark so that one generally requires a light, this light does NOT come up. I am now tired to setting up the LUX meter continuously for two day to set it my desired level!

Must Buy,!

It turns on power or occupancy and then turns off after some time even though motion and occupancy is there. Once again it will turn on if you wave hand. It is really annoying and not worth of the cost. Better check for other ones.

It's really a great product and quality also very good
