Sensky 360 Degree Ceiling Mount Occupancy Sensor, 110-240V PIR Motion Sensor Switch, High Sensitive Movement Detector Light Switch, Neutral Required(Max Detection Distance: 6 m)

Works perfectly, better than expected . So I purchased another one.

This is my second purchase of this product - which tells you I think it is worth buying. If you are not at least a little bit handy you might have trouble installing this switch as there are two minor deviations from US standards. First, the color coding of the wiring is not the US standard for switches that are offset from the main line to a lamp (that is, the switch is at the end of a spur off the wire feeding power to the lamp) That standard is to use a 3 wire (plus ground) cable for the spur with Black=Hot, White=neutral, and (typically) Red=return of the hot signal to the main line. In this device the three colors are brown, blue, and red. Please read the included documentation to see how to use these 3 wires (if you can't do that you should not be installing this yourself). The other oddity is that the screw holes in the base plate (not shown) are not spaced to attached to US standard junction boxes. That was easily fixed by drilling an extra hole in the plastic base plate but again, if you are not at all handy, this could throw you.

Installed this in a drop ceiling in a 24x24' room on a 9' drop ceiling. Works very well with activating on pretty small movements. Only flaw I have is it gets triggered in middle of the night by the heaters coming on. There's no way to adjust sensitivity to motion, just ambient light and how long its on.

Used for hake year. Good quality, easy to install.

Not very sensitive. It works, but does not trigger and since there is no diagram if the sensor ranges, hard to figure out best placement. Might be fine for large open area but not if objects like cars present (garage)

It Works fine, easy installation

It detects motion if you jump like a monkey within 10 ft. I purchased this for motion sensing at night. It is useless It works only at a larger distance in daylight The adjustment for day or night detection does not make any difference

Works well. It’s pretty big though.

Received item in good working condition.

I use it for my spiral staircase. It can and it reacts both going down and up. Normal sensors would not work.I wish the mounting holes were distant enough to screw directly to a duplex box. (I made a hole to mount it)

ممتاز اشتريته من سنة ويعمل بشكل ممتاز

Not worth the money, the sensor went bust in just 3 days of use. Last night it switched on with no one walking in the lobby where I have installed. Despite the proximity sensor adjustment it switches on Iin broad Daylight and at night when no one is walking. Not worth the money. I had bought it thinking Amazon would ha e a solid quality control.earnt the hard way it is not. Will go for more branded and expensive product like Schneider ARGUS.

I was concerned that the sensor would be too sensitive -- from what others were saying -- but it's not. I use it in the basement where the light switch is all the way across the room, but sometimes I need to put a light on in the room before, just so the sensor can 'see' me. Still, I love it and would buy again if I needed to. Highly recommended!
