I've been looking for exactly this type of motion sensor control for a long time. The last one I tried almost works (not sure the brand) and looks exactly the same be behaves differently - it would turn off the light after the delay time, even if motion was detected - the light would be off for a few seconds and then would trigger if I waved my hand. So no matter what I would be in the dark for a few seconds. This one (ECOELER) will do something we in electronics would call retriggering, if any motion was detected before the end of the delay time, it would re-start the delay time, no dark time - lights would stay on until no more motion detected and the end of the delay time was reached. I've tried this on 2 of the units I've bought and both behave the same and quite reliably - some have stated they got false triggers (when it turns on by itself with no motion detect), I did not see any false triggers so far (been using for about 3 weeks now), always turns on ONLY if motion detected and always turns off after about the correct delay time. I'm using this on LED lighting (didn't try any other types of lighting or load), no problems. I DID set the sensitivity and ambient levels both to 5 (maybe this caused false triggers for some people). I didn't need ambient so I set it to 5 (instructions say this is off)(ambient allows the light to stay off if there is already enough background light). I didn't need sensitivity so high but it seems to work anyway (I only need short sensitivity but don't mind long so I set it to max long, 5) - it seems to have about a 90 degree detection cone (+/-45 degree from center). Time delay I set to 1min at first and this worked ok but a bit too short, now set to 5 min and this is just right for me. Note that all three of these settings are analog rotary trim potentiometers (variable resistors) so they are approximate.I only used occupancy mode, did not try vacancy mode(my understanding is vacancy mode means manual turn on, auto time off with no retrigger, that is, it turns off after the delay time, motion is not detected or used). I can see how this may be a useful feature for some but not for my case, I wanted hands free operation and in one case, the switch is located far away, awkward to reach .I've only seen this type of retriggering motion detection on an outdoor security light and that one did not always trigger properly when I moved into range, and I think it was much more expensive (but it was a whole fixture, not just a wall module).Another type of motion detector I've had used a separate wireless battery (3AAA) sensor that sends a signal to the main controller. This worked reliably but needed to change the batteries every year and eventually I forgot, and when I remembered to change them, the batteries had leaked and corroded the guts. Also it was NOT a retrigger sensor and so it always left me in the dark for a few seconds before the next trigger (not really bad but still annoying). Now I've switched to this ECOELER and won't look back.This is the BEST, highly recommended!

This has all the features which I like in a motion sensor light control switch which is not dimmable. It works in any single gang receptacle. It has a light detection setting to set the diminished light level at which you want it to start working which is easy to use and works excellent.It has a motion detection setting which adjust the range at which you want the sensor to activate the light. Very useful to set to where it is not activated by movement in an adjacent area.It has a setting for the length of time it will stay on once no more movement is detected which goes from 15 seconds up to 30 minutes which is easy to set and works fine.There is a green led which flickers when it detects motion.The switch can be set to work manually but the light will still go off at the time set for after movement detection has been reached.It is quality made and looks fine.I have installed several motion sensor light switches and this is one of the best for a very low price. I highly recommend it.I am an electrician of many years experience.J W

This sensor is good, but I just gave it 4 stars because it doesn’t have a long time when you turn on lights, so you have to stay continuously moving for the lights to stay on. Otherwise the installation is easy, look good and are functional! Definitely worth the money.

I needed a sensor that would turn the lights on as soon as I walked into our garage, stay on as long as I was in there, turn off a few minutes after I left, and then turn on again even if I walked in 1 second after they had automatically turned off. I first tried the TOPGREENER TDOS5 sensor and wasted hours trying to get it to turn back on after automatically turning off. Maybe I had a dud, but I suspect bad design. If the timer was set for 30 minutes, the lights wouldn't automatically turn back on until they had been OUT for 30 minutes. Very frustrating!I then ordered this Ecoeler sensor, which happened to be $4 less, and it works EXACTLY the way I want it to. Win-Win.To be fair, there were a couple of setup issues. The ambient light detector was too sensitive for my purposes, and the lights wouldn't turn on with even a small amount of light in the garage. I turned the light adjustment CCW thinking that would be minimum sensitivity. I had to read the instructions to find out that you have to set the pot fully CW to "5" to disable the light sensor. I almost deducted 1 star because they made me read the instructions! The second issue was with the range adjustment. The sensor is next to the door and I need it to detect someone as soon as they step through the door. I had to set the range to minimum (CCW) to do that reliably. Now the maximum reliable detection range is only about 15 feet, but I can live with that. Overall, I'm very happy with this purchase!

This motion sensing light switch is only useful in its OCC mode - where the lights automatically turn on because of motion. For this reason I'm giving it 3 stars as that's probably the use case for most people. Works well in a laundry room, pantry, closet, etc.But if you want it to work where you can manually turn it on and also potentially manually turn it off, it's broken by design. It'll only work to auto turn off due to lack of motion. If you manually turn it off, IT'LL TURN RIGHT BACK ON DUE TO YOUR MOTION TURNING IT OFF! 🤦🏾‍♂️🤦🏾‍♂️ The only way to successfully turn it off is hiding and being motion free when turning it off making it impossible to use in a bedroom, shared bathroom, etc.Ended up returning it and getting a different one that was easier to install (no neutral required) and most importantly worked as expected.

Response time to activate light is much better than previous sensors we have had. We checked to make sure that we had a common wire before purchasing. Product was very easy to install. Took 10 minutes for my non-handy husband to install.
