Leviton ODC Series 2000 Sq. Ft. Multi-Technology Ceiling-Mount Occupancy Sensor, 120-277 Volt, White

Far better than the RAB motion sensor ($80) I had... which failed 3 weeks in to use and kept the lights on all the time no matter how low the sensitivity was set. The dual technology is great with this motion sensor. I was even having false set offs with this because of heat movement in my basement. So I lowered the IR sensitivity and raised the US sensitivity and it's perfect with no false set offs anymore.Installation was moderately easy. If you know how to do wiring, as I learned, it's not too hard. You will need an octagonal or square wall box with at least 2" depth clearance for wiring.The only caveat is, and the reason I gave it 4 stars, you can actually hear a very low shrill sound with the US. I do mean a VERY LOW sound. Since I use it in an area that is high traffic with little to no lingering it's not something that annoys me, but if it were to be in a room that I had to stay in for a while then that sound would annoy.The cost is high compared to other sensors, but the quality is far greater as I have come to find out.

This multi-sensor unit placed another simpler Leviton occupancy sensor that failed by turning on and off randomly. The ODC05-MDW is a complicated device but if you read the instructions you'll be fine. My application used most of the default settings. This is 120vac unit - no AC-DC converter needed. You do need a octagonal electrical housing of size 3.5" by 3.5" by 2" deep. I could not reuse the round electrical mount that my older Leviton used. I have attached the old-work octagon housing I obtained which is ready for the ODC05-MDW. I have also attached a photo of the original mount that didn't work with the ODC05-MDW (note the cover of the ODC05 is removed.I wanted a sensor that would immediate turn on in a hallway then shut off a few seconds later once I've left the area of the washer and dryer. And it does that perfectly. I'm only using the motion sensor mode, no IR (heat). The reaction time is very fast which a pause or delay from being in the area and the light being turned on. This unit works so well my next project for it will ditch the light switch.

This was insanely easy to install - with no complex wiring whatsoever (using normal, 3-wire romex). You simply put this before your lights in the circuit with the load wire clipped into each side of the relay, and then T-the neutral into the neutral spot. That's it (I attached an image of the instruction booklet which shows this perfectly). Took me a total of about 10 minutes, and I'm not a wiring expert by any stretch.Now all the lights in my garage (35'x 20') are controlled by the sensor, and it works incredibly well, is sensitive to motion, and generally meets every expectation I had.

It works better than the one that it replaced but it is a bit confusing. It is not quite as easy to set up than others.Note each occupancy sensor has different characteristics. I chose this among others in the manufacturer's catalogue because it best fit our needs in our family room - TV room,It has several filters to make it more suitable under varying ambient lit situations.I encourage you to download the instructions and read them before you buy one. If you have no trouble visualizing them, then it is a 4 or 5 star product.

I have one of these in my server barn controlling four eight foot long fluorescent fixtures ( 16 bulbs total ) - somewhat over five hundred watts of lighting. The unit works flawlessly turning on the lights as soon as the door is opened and turning them off a short time after I leave. Considering that I pay twenty one cents a kilowatt hour for power, this saves me a lot of money. I also don't have to stumble through the snow to turn the lights off when I go to bed.I'm going to get a second unit for my garage ( same lighting load ).

I use it to control my split 18000 btu ac unit. Bought it in 2016 but installed it 3 months ago, works perfectly so far.

Bought this item to wire up my parents garage with a motion triggered light after somebody siphoned off a whole tank of gas out of their truck, and itso far, appears to be working well. It is so sensitive it can trigger on flying nightime bugs. I am so totally impressed with its' sensitivity that I amconsidering buying it myself. Excellent product in my opinion.

Works very well, extremely responsive and few false positives. This works far more reliably than a wall-switch mounted motion sensor.The only issue with this sensor is that it will NOT fit into an "old work" box.
