MEW-OS100W

Product works great - I have purchased three of them and installed two so far. I thought I had an issue with the one in this photo installed in the garage as it was coming on at night and staying on all night. After some testing, it turns out when the camera's infrared lights came on at sundown, it triggered the motion sensor and kept the lights on. Sensitivity was set to 3. I set the sensitivity to 1 and will see if the lights still come on this evening. If it does, I will just turn off the infrared light on the camera - as any motion will turn a light on and allow the camera to see. I will continue buying this product any place I want lights to come on when entering a room.

During the ADA restroom upgrade at our church, I decided to add this occupancy sensor. We found it works quite well (turns the lights and vent fan ON just as you enter the doorway). The restroom is 12' x 8' with a low (7.5 foot) ceiling; the sensor is located near the center of the ceiling. Even with the low ceiling, the sensor still has plenty of range to monitor the doorway and the entire restroom. It has three adjustments (TIME, SENSE, LIGHT). The time and sensitivity adjustments work well. Our restroom does not have any natural light, so we cannot comment on the 'light' adjustment. However, for applications with plenty of light from windows, this knob would be useful to set the dusk/dawn light level at which the room lights function (rather than turning lights on when not needed). Wiring was simple. Instructions are adequate and written well enough for the DIYer to get the job done. The product performs quite well at this price point... One minor improvement: I would suggest increasing the hole spacing in the mounting ring... It is presently a bit shy of the 3.5" spacing between the 8-32 screws in a typical octagon electrical box. I had to tweak the holes in the plastic to ease mounting. BTW, the provided flathead screws are needed to attach the mounting ring to an electrical box, or mounting surface. Otherwise, (with round head screws) the sensor will not have enough clearance to twist-lock into the mounting ring.

I like the appearance after installation on a public restroom ceiling but have found that the sensitivity adjustment is not very linear and is either too sensitive or not enough. It senses too well though as even a flash of light in the room will start it. Like a car headlight hitting the no see through windows in the dark restroom room turns it on. I have attempted to mask the sensor lens to overcome some of these false triggers but am still working on getting it to a dependable state. Also is very sensitive to heat or cold registers entering the room. It is a high bay sensor as advertised and requires a fairly high ceiling to work property.

Didn't even make it a month. I had, over the course of multiple days, to fine tune adjustments until it worked how I wanted it, at night, with no false triggers. But now for some reason all night it has been going off pretty much non stop even though there is nothing within sight and the light and sensitivity dials are on the lowest settings. It's 2:30 in the morning and I just about ripped it out of the ceiling because it's been keeping me awake with the constant clicking on and off. It was easy to install though.

Works great, good sensitivity. Easy to wire in, no delay or flicker with LED's

like the Tital states. it just works perfectly. you have plenty of adjustment for light and sensitivity. open the door just a few inches and the light turns on with no issues at all. very simple to connect up.

Totally my fault… I didn’t look at the actual measurements for this. Way too small for what I was needing. However it is well packaged and I am sure would work well as we have bought other products from this maker and like them.

Just installed it, so I don’t have any history to share, but it is working fully to my expectations. Sensitivity is set at 50% and detects movement in my 2 car garage.

Very happy to receive it in time and good conditions. Thank you!
