Sensky SK037 3-12M 360度 天井占有センサー PIR モーションセンサースイッチ 高感度モーションセンサー ライトスイッチ(110V-240VAC)

Great product

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.
