SENSKY BS010WL DC 12v to 24v Mini Pir Motion Sensor Switch Occupancy Sensor Switch for DIY LED Lighting (Light Sensor, Delay Time, Sensor Distance, Adjustable)

I bought this to control led strip lights in a small closet, and I bought this one with the light sensor thinking that it was the version that you can turn the light sensor off, but I was mistaken. The closet is small enough so that when you walk in, the sensor detects you and turns on the light, but then it detected the light and shut off; then it realizes it's dark and turns on the light and shuts off again. I was about to return it when I realized that the entire circuit board slides right out. Under the translucent dome are two sensors; the center, square sensor detects motion, the round sensor on the side with the wavy line is the photoreceptor. I covered the photoreceptor with a tiny square of electrical tape and now it works perfectly. Please note: this is not a defect in the device, merely a side effect of having lights and a light sensitive sensor in a 2' x 5' space. The motion sensor works very well, the delay is adjustable, and I intend to buy more. Also, the delay on mine was set to minimum which also caused the light to flicker off and on but adjusting it even slightly more positive fixes that problem. It is a completely silent device, which was important to me, as the motion sensor switche we have in the master closet has an audible click when it activates the light (that one is a $29 Lutron Decora). Another note, it's much smaller than I thought it would be which is a huge plus! One last note: I'm using it with the Pautix LED strip that comes with its own remote that dims the strip; if you dim the strip to your liking and walk away, the LED strip remembers the last setting so you don't have to adjust it every time. I couldn't be happier with this setup over something like a WiFi hub installed product.

This little switch works wonderfully! I use it as a motion detector in my home's entry-way to turn on 2 meters of LED strip when you walk in the door after dark. It is unobtrusive and always works correctly! I saw some reviews saying that there was no way to adjust it, but I had no trouble: you simply pop off the back of the case with a small flat-head screwdriver and the three blue dials are all immediately visible and accessible. The sensitivity dial controls how close you have to be to the sensor in order to activate it, and I set mine to about the halfway point, so it wouldn't trigger when someone walked down the hallway a few feet from the entry-way. The delay time dial controls how long the light stays on once it gets triggered, and it is super sensitive! Just a degree or two can change the amount of time by several seconds! The Light Sensor dial controls the lighting threshold. What I mean is that it sets a light level that the sensor bases its operation around: if the ambient light (the amount of light already present in the room) is below the threshold, then the sensor will allow itself to be triggered and turn the lights on when it senses motion. But if the ambient light is above the light threshold, you can't trigger the sensor and it won't turn on. This turned out to be an incredibly useful feature for me, because it allowed me to play around until I found a value that starts triggering the sensor around twilight/dusk. A quick tip for using the adjustment dials: When you are trying to figure out your values for the Sensitivity and Light Sensor dials, have the delay time set to its minimum value, otherwise you'll be wasting a TON of time waiting for the lights to turn off to try new settings. Also, when you pop the back off of the sensor to get at the dials, be aware that the sensor's circuit board is not actually screwed into place inside the housing, and so will fall out if you turn it upside down... Now, I didn't find this to be a problem for me, but it may disconcert some people, so just be aware. Because of how useful these little sensors seemed to be (as well as how cheap they were!!!), I bought 2 of them on my first order and boy am I glad I did. Now I have set them up at both my front and back doors, and I'm even thinking about setting one up for my internal garage door! I really can't praise this product enough! Just keep in mind that they were never meant to control an entire room full of LED lights; the maximum current on this thing is only 3 Amps, so don't overdo it!

This item solved a problem I had lighting a long, outdoor walkway on the side of my house. I needed an easy way to illuminate the path for people coming from either direction. The problem was that most motion lights could not monitor both sides of this walkway easily, or if they could, they would only control a spot light which was too harsh for my installation. I could have also used high-voltage motion sensors and wired them to an outlet, but then I would have had to install conduit. By using low voltage I was able to install them using small wires and zip ties without needing conduit. This replaced a couple of Insteon SmartHome motion sensors that broke over time. Since the company has since gone out of business I found that I had to DIY if I wanted to control the existing lights in a similar way. Using these, I was able to replicate the function of the Insteon motion sensors. I hooked two of these in parallel to a 12volt relay that was wired to an independent outlet in which I plugged incandescent rope lights. The lights were run the length of the walkway. Since there is one of these motion sensors on either side of this path, a person could approach from either direction and the rope lights will turn on (and anything else plugged into that 'controlled' outlet). I could have just used 12v LED lights and not needed the relay, but I already had the lights installed and wanted the flexibility to change them later on.

Used this for under the cabinet lighting, and wanted it to turn on when someone came in. Works really good. It was picking up movement across the kitchen. Adjustments were finicky but was able to bring it down. Over all, good buy.

The first one I received smelled like burnt electronics, and was slightly melted on one side, before even installing it. After I installed this initial one it just stayed on all the time. So I requested a replacement, the replacment works perfectly. It has the same plug ends as our AIBOO under cabinet LED lighting switch, so it was easy to just pulled the switch out and placed this in place of it for our laundry room, now as soon as you walk in these under cabinet lights come on, and shut off approx 1 minute after leaving. I will upload some pictures showing this setup. I had originally planned on using the remote for the cabinet lighting, but since we have similar lights in our kitchen the remote for either module would turn on the both sets, so we removed the module and have been using the switch, but this is a much better solution then the switch mounted under the cabinet.

Love it. In the box is a diagram that shows what each set-screw/rheostat does: You can control- How long it stays on At what brightness it will come on at WHEN it detects motion. It Detects motion, set-screw to set the sensitivity of the motion sensor. Now, I did have to buy a LED dimmer dial thingy - because without it, the strip light was basically auditioning for a Playboy Bunny Bar. With the dimmer, it’s perfect—soft glow, no interrogation vibes. Middle of the day? No light. After sunset? Boom—low glow. Installed it as a base‑cabinet LED strip nightlight in the bathroom. And now, when I stumble into the bathroom at 2 a.m., it politely flicks on dim, waits 30 seconds, then shuts off like it’s saying: “Alright buddy, you’ve done your business, back to bed.”

Seems tricky to adjust, but it’s actually pretty easy! Works great for my garage bathroom light!

I have needed to order twice as many as I need to account for the units which turn on and never turn off. The output transistor appears inadequate, in my estimation, and overheats and promptly fails "ON". They are small, and when they work are very nice for undercabinet use. I wanted a unit with enough range to only pick up motion when a hand reaches under the cabinet to do something, not when merely passing by. Also the timeout ( time until connected load turns off) can be as short as about 10 seconds.

I used these to turn a set of Govee LED strip lights into the perfect automatic closet illumination! I love the fact the sensitivity and duration can easily be adjusted.

I bought some of these do use to activate a custom LED strip within lower cabinets with a long lazy Suzan / pull out. I have only implemented one so far. While it does take some experimentation to set the on time, so far it has been working very well.

works... fast delivery

Terrible sensor and didn't work at all plus has 3 settings with the dials which didn't help at all the lights stayed on and never shut off. Tried all the settings 👎👎👎

This has been fantastic. I walk into the room and my LED lights automatically turn on. Great upgrade for LED lights and well priced.
