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)

I like that the adjustments are on the outside of device and easy to get at. I also like that there is a light that indicates when it has activated. Works well.

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.

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

It works and it’s cheap. Although, after a year of use in my garage I’m often frustrated. It works better during the cold months, not well at all when space is hot. It’s passive infrared sensor doesn’t differentiate body heat from all the other hot surfaces in my garage. But, the one I installed in a bedroom closet works great! FYI - Installing the sensor over a typical plastic single gang cut-in box reveals the box is larger than the diameter of the sensor. In my photo the corners of the box are visible. A round cut-in box would have been a better choice for this application in my closet.

I'm an electrician and I've always installed the $80 name brand motion sensors. I gave this a shot in my house and I love it. I looks better than the expensive ones and works just as well. My only complaint is the way there wires are meant to come into it doesn't work, it would pinch then and short them out but there are other ways around that.

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

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.
