QWORK Motion Sensor LED Switch (2 Pack), 12-24V, 6A, Adjustable Delay Time, 5-8M Induction Distance, 60° Field of View, for LED Strip Lighting, Wall Mount, 3"

I used it to control the led light strips I installed in my RV basement. Works great! Good value for the money.

At first it didn’t work, similar to other reviews. However, changing the polarity +\- fixed the issue. They need to make this clear in the description as there are no instructions or labels

I only needed one motion sensor but purchased a 4 pack due to some reviews complaining of reliability issues, so I would have spares. As background I have 40 years experience with advanced electronic systems and these are very simple devices. I first tested my 12v DC power pack directly connected to the LED strip I want to light up with motion detection. Perfect, no problems. I then connected into the circuit one of the purchased motion detectors EXACTLY as instructed, taking note of specified polarity. I set it up in a clear line of sight location for testing. Dead in the water, does not light up the LED strip. In other words human motion in front of the unit did not activate the switch inside the motion detector which should then pass on the operating voltage for the LED strip. I then tested the remaining three motion sensors I purchased. NONE of them functioned. An additional peeve for the electronics pros in the know is that while the product advertisement does state 12-24 volt power supply it does not specify AC or DC...or either. All LED lights actually operate on DC voltage only, if the source voltage applied is AC, for a device compatible with powering LED lighting, there would be an internal full wave rectifier to convert the AC voltage to DC voltage. AC power supply outputs do not have a polarity. These motion sensors are stamped with - and + markings on the casing and also referenced in the instructions which in the electronics world indicates that it would function ONLY with a DC power supply. If a device compatible with powering LED lighting can accept an AC input there would NOT be - and + markings on it. In other words the - and + markings and instructions on these motion sensors would indicate that a DC power supply is REQUIRED. Not sure if that is actually the case or not but the seller should specify what's what. Such as stating 12-24 v AC or DC...or 12-24v DC only for example. If it's AC compatible there should not be polarity markings or instructions.

All four working as described

One didn't work (never turned off) and the time adjustment is difficult to already without damaging the adjustment screw itself. Aside from that, for how incredibly cheap and easy it is to use you can't beat it. I'd be fine buying another set to replace the one that didn't work and I'd still be paying less than the next cheapest option out there

The QWORK Motion Sensor LED switch works perfectly. Now I go in and out of my kitchen holding things in both hands and I don't have to fumble for the light switch. Since I live in a solar off grid home, conserving battery power is essential. Positioning the sensor correctly is important. The item price was good too.

I installed one on my solar combiner box to turn on an amber led strip to light the interior while using the controls at night.

Installed 2 of these. One in my RV pantry & one in a storage bay. Installation is easy however the time delay adjustment dial is recessed in a very small hole and difficult to reach even with a small screwdriver. I found it hard to know if I was actually turning the dial. The dial on one of them ended up getting bent against the internal circuit board. After easily removing the cover with just 2 screws I was able to adjust the dial with my fingers. However then the switch wouldn’t turn off.

J'ai utilisé ce produit pour la commande de lampe de bureau. Fonctionne bien.

Buen producto, la pena es que solo es de 3 A

I purchased the Qwork motion sensor LED switch (package of 4) and not one of them works properly!!! Connected to a 12V led strip light - very simple little setup. They will turn the lights on initially at first when movement is detected and will turn off 20 minutes later. Tried adjusting the timer control but its useless, will not work. Tried all of them and none of them work. I wasted 2 hours of my life testing them. No idea how all 4 of these things are shipped failed or damaged.

Sehr gut verarbeitet und funktioniert perfekt
