Sensky360 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 as expected

The motion sensor works great. I put it in my closet because my wife never turns the light off. The sensitivity setting and timer setting work for what I need. The light comes on even if the area is already lit and turns off about 2 minutes after it no longer senses motion.The instructions are another story. I really wish the Chinese companies that make these products would hire a person who grew up speaking English and not someone who speaks it as a second language. It took me a few minutes to figure out wht they were trying to say and understand the wiring diagram well enough to install the switch. Once I figured it out it was fairly easy to install.

I have one high hallway light that I tried two other expensive motion detection sensors. Neither were reliable. This model worked perfectly since installed and has been flawless for nearly six months. I can’t recommend this unit highly enough. It seems as though it would have no problem being mounted outside in the elements, but I haven’t tried that. Also, I haven’t tried large outdoor spaces. What I can tell you is that this detector has been rock solid.

Several issues: the mounting plate holes do not match a standard US ceiling box. It comes with an unnecessary terminal connector that requires a tiny flat head screwdriver. The directions are very poorly written and hard to understand. It's really not that sensitive. I'm finding that you get what you pay for with motion sensors.

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.

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.

This thing only worked for two weeks. The light turned off after few minutes as expected, but a second after it turns on and never turn off again. This is inside a closet so no movement inside the closet after doors are closed. I am not returning this because the time to be spent returning it is not worth it, I am just throwing it away.

Installed in clothing closet, works great. The installation instructions were terrible, but I followed the instructions correction others posted here.Worked perfect and inexpensive.
