SENSKY BS010L Mini PIR Motion Sensor Switch - DC 12V to 30V, 3A Output

JR-55: Used to turn lights on inside a safe. Easy to install and adjust, Turns them on when door opens, stays on as long as motion in front of door. I set the turn off timer to about 15 seconds after I step away from the door 6-8 feet or after door is closed. Lowered sensitivity to reduce distance but still very sensitive. It works great.

dustin l.: The adjustments are finicky and I don't think it even works anymore after just a week. Feeling mostly disappointed, especially with how hard it is to troubleshoot.

John S.: Taking the back off to adjust the sensor was a bit tricky. At first I couldn’t get it off and couldn’t get the sensor to stay on for more than a second. I went back and retried after rereading the instructions and finally managed to get it off. From there it worked well. Four stars because getting the back off was not easy and I was concerned that it would break in doing so.

warthorn: Works as described - put it into an appropriate volt/amp system where the lights are left in the "on" position, and this accurately detects your presence and completes the power loop. It was very easy to add into the existing power system of an LED light kit.

Two elements are inconvenient. First is popping open the plastic case and working tiny knobs to set its sensitivity -- realistically not a huge problem since you'll probably only need to set it up the first time, but you'll end up taking it apart a few times to get it dialed in. Nothing broke which is more than I can say for many plastic-clip based doodads like this. Second, the mounting screw holes on the sensor are super tiny. This really limits the types of screws you can use. Tiny screws are very annoying for seating into wood, or even some MDF, without stripping. My suggestion is while you have it apart, drill a small hole or two into the back side of the plastic case (behind/below the circuit board, not touching it) and screw it down that way -- I cut the factory screw holes off mine with a razor blade to make it fit flush in a small space.

One other quirk, I've noticed either a decline in the width of its...

AnonymousAnonymous: I think it works well.

I probably bought this for the wrong purpose. I'm using it to trigger a camera for home security.

I used a voltage divider and I'm able to read the ~12.23v dropped down somewhere around 3-4V with an ADC in my case MCP3008 with 5V reference. I'm able to trigger the camera with a 300ms delay using Raspberry Pi's built in raspistill command and python os.system to call that command otherwise ran by exec() on command line.

Anyway it works for me. The range was not as far as I would have liked, I'd say 20 feet was hoping like 30 but oh well. It was tricky to turn the potentiometers at the back for adjusting sensitivity. The light pot for example I don't even know how to use it in real time. I set the delay to lowest possible and then had it connected to a multimeter to see in real time where (how far) it would trigger, where it would shoot from 0.01V to over 12V.

update:

now that I'm actually using this thing, I'm not sure how reliable it is, it seems to randomly fire despite the low (0) analog readings and the room is empty (no motion/changes) so I'm not sure, will see if it's the light possibly but even that is constant...
