Strip Light Motion Sensor Switch, DC12V~24V Infrared Motion Sensor Detector Switch for Cupboard Cabinet Kitchen Stairs (2 Pack)

The first time I wired it I guess I didn't have the wire in there enough. I wired it to 12v power supply and now I have led lights that pop on in my closet then I open the door. Very nice. I would buy again. The little screws that hold the wire in moves a tab that compresses the wire in the frame of this unit. Take a second to see what way the screw is moving before you get too excited. I turned the screw the wrong way and it was loosening not tightening. Of course 50/50 chance and I got it wrong. All in all it was a 2 minute install. Used wood screws to where i needed it. Nice!

First off... I am using a 12vdc power supply for a short run of LED lights in a pantry. The lights I bought didn't have a motion sensing function so I decided to add one. My initial wiring was in the wrong polarity unwittingly and the light would not go out... By mistake I had set up my meter wrong and polarity was 180 out. This item works perfectly once the short between the headset (in my head) was corrected. Great product

Update: I have done further testing on mounting the sensor facing out and it has made the sensor response time and motion sensing much better. I should have known better. I have updating my rating to reflect this. ---------------------------------------------------------------------------------------------------- The first order contained a bad sensor (the switch never opened to turn off power). This was replaced with another pair of sensors in a somewhat timely manner. No issues here, acceptable response from the seller. I am using the sensor for cabinet lighting and I have mounted it both the horizontal (sensor facing down) and vertical positions (sensor facing outwards). The response distance is not as indicated on the product page (5-8 meters). In addition, the response time is very slow; I have run into the room and wave my hand directly in front of the sensor for at least second or 2 before the sensor identifies motion. The product descriptions is as follows. 【Wide Application】: You can use this sensor in different occasions like entryway lighting, cabinet lighting, gun safe lighting, pantry lighting, under the bed rails lighting. 【Delay Time Adjustable】: 1-10 min(adjustable). Induction distance: 5 ~ 8M 【Motion Activated】: Sensor function triggered by motion, you can use this small motion sensor switch to control lighting like Led strip lighting. 【Warm Tips】：Users can install the human body sensors in the appropriate environment according to actual needs. 【What you get】2PCS DC 12V/24V Body Infrared PIR Motion Sensor Switch I have contacted the seller about this and below are the responses. "Thank you very much for your reply telling me the problem you encountered. The theoretical value of our sensor is 5-8 meters under normal temperature, but the actual range of induction will be lower with the temperature decreasing or obstacle blocking. The theoretical detection range of the sensor switch at room temperature can be referred to the attached figure below." Temperature is not an issue. I live in Florida and the climate is quite warm here. "The corresponding time of the sensor is set by the manufacturer. We have not tested it, but the corresponding time changes with the temperature change. The low temperature will affect the effect." There is not a low temperature situation here. "The response speed of the sensor is difficult to calculate. Because the sensor has detected movement, the switch is working immediately. I don't know where you are actually installed. If it is used with the light strip, I don't think it is necessary to know the response speed so accurately. If you really need to know the response speed of the sensor, I can try to help you to ask the manufacturer." Either way I am going to work with what I have been supplied here. Not great but acceptable for now until I find a better solution.

I like the solid construction all around and very reliable motion detection. They turn on right away. The only fault I can find is the "stay-on" time ranges aren't exactly 1 to 10 minutes, but they're close enough for me and probably most users, so they still get five stars. One of my units has a "minutes:seconds" range from 0:21 to 7:55 and the other from 0:22 to 9:18. All of those timespans are repeatable per unit to about 5%.

After 2 months 1 quit working

Using these to turn on my under counter lighting in my trailer. It is all 12VDC, and I put an LED strip under there to give me a better lighting option in my trailer. So far, this has worked out super well, and it has a time delay adjustment screw to adjust the on time before shutting off if no motion is detected.

Good

Bought this so I wouldn't have to worry about the lights being left on in my 40' container. I'm using solar power to run the LED's in my container. Occasionally, the switch would get left on overnight. This sensor stopped that issue. Easy to install. No more worries about the battery getting run down
