Sensky 360 Degree Ceiling Occupancy Sensor PIR Motion Sensor Switch with 3 detectors,10-40ft High Sensitive Ceiling Motion Sensor Light Switch(110V-240VAC)

This device worked perfectly for my garage lights. I had previously changed out the old inefficient fluorescent tube lights with LED shop lights. The problem is they kept getting left on, which still burns power. By adding this switch in series with the wall switch (which we now leave on all the time) the garage light turn off after ~10+ minutes after you walk out. Exactly what I wanted. It even senses if the garage door is opened when we use the remote and turns on all the lights. It was relatively easy to install.

Work great

I added lighting to my pantry and to my hall coat closet. I purchased Senski motion sensors for both applications. Installation was straightforward, and the same as most motion sensors. The instructions are a bit difficult to make sense of, regarding adjusting the three different adjustment knobs on each sensor. I just kept messing with the adjustments until it worked as I wanted ( light on when door was opened and sensed door motion). It would be 5 stars aside from the adjustment instructions..,

The first one I bought malfunctioned and I had to buy a replacement.

So I bought one and I took a while to install it. Over thirty days. It had a glitch so when you entered the garage it would come on then when you came out to the garage it would go off you have to stop cause you are in the dark maybe 15-30 seconds later it would come back on. Then it would stay on as long as you were in the garage. It had good range but the glitch was super frustrating. I just put up with it for a while because I was outside of the return window. I gave it a second chance and installed the second one quickly just in case. It's working great, no glitch and they do a great job of picking motion any where in the garage.

Easy to install. Sensitivity adjustments made it very versatile for my closet light switch application.

Too heat sensitive because of cheap, heat-sensitive components inside. Adjust it at 75 degrees and it doesn't work at 40 degrees and vice-versa. Good idea but built so cheaply that it just isn't reliable or predictable. Either it won't turn on when you want it to or it won't ever turn off. Buy something else.

Put this in the laundry room so that we didnt have to worry about the light. It took a few days to get the setting right but we have really enjoyed it for the last few mo ths.

Great product
