💡 Invisible tech that’s always watching—light up smarter, not harder.
RELIABLE COMPLIANT - CSA, UL, FCC certified with Title 24 compliance—trusted performance for commercial-grade environments.
SEAMLESS INTEGRATION - Ultra-compact design blends invisibly into ceilings for a sleek, modern look.
EFFORTLESS INSTALLATION - Quick ceiling mount with simple three-wire low voltage connection and twist-lock sensor for hassle-free setup.
ADAPTIVE LIGHTING CONTROL - Built-in photocell senses ambient light to prevent unnecessary lighting, optimizing energy savings effortlessly.
SMART OCCUPANCY DETECTION - Multi-technology PIR and ultrasonic sensors ensure lights activate only when needed—no more false-offs or wasted energy.
The Leviton OSC10-M0W is a compact, ceiling-mounted occupancy sensor featuring multi-technology PIR and ultrasonic detection with 360° coverage up to 1000 sq.ft. Operating on low-voltage 24V DC, it includes ambient light sensing to prevent unnecessary lighting. Designed for fast installation and commercial reliability, it meets key certifications including CSA, UL, FCC, and Title 24 compliance.
Bought 1 of these Leviton OSC10-M0W sensors with an OPB15-DW base. Overall I cringed a little at spending ~$100 for the pair compared to what you can get consumer-grade wall-switch-type sensors for, but am very happy with the purchase; you get what you pay for. Note that pricing of these varies considerably depending on where you buy them.Really like the technology of PIR for initial turn on, then both PIR + US for keeping on.Also really like all of the options and adjustments that can be made.Also happy that load is switched via relay vs electronic components; had trouble in the past with latter-type swithes being destroyed when the incandescent load burned out ($1.50 lamp but $30 sensor after less than a year). This also avoids problems with non-traditional loads: CFLs, LEDs. Also note the zero-cross switching technology in the base and power pack products.I put this up in an unfinished basement laundry room area which was impractical for a wall switch-type occupancy sensor. Was expecting problems as it is around a washer, dryer, dryer vent, sometimes-moving clothes hangers, furnace, and water heater. But it has performed perfectly.So I will be ordering another sensor+base for the stairwell/pantry area of the same room.Note that this is part of a line of sensors; check them out at leviton.com for different models that may match your situation better.

Worked well
Good product and I appreciated the many settings. I ended up turning off the ultrasonic since it was in a commercial kitchen and the ultrasonic picked up noise from the refrigerators. However, it is now working quite well.

Line voltage vs low voltage
Beware to the buyer this particular item is a commercial grade low voltage detector. Meaning it will not run off of regular 110/120 voltage that most houses use in the US. I called up Leviton and found out that this particular sensor needs a transformer to lower the voltage so that it can be used. The transformer is quite large and will add to the space requirements for any ceiling mount installation. Basically, do you really want to cut out even more drywall? For a motion sensor with the transformer all in one unit, look at these units: ODC05-MDW, ODC10-MDW, ODC20-MDW.I had to return mine and because of my electrician already charging me the day for work, I had to find a local electrical supply store and get whatever sensor they had... Beyond angry... so now I have a subpar motion sensor hooked up. Will wait a while before upgrading to the Leviton which from the spec sheet using ultrasound and passive infrared sensors seems a lot better than the RAB motion sensor I now have.Buyer beware of the spec sheet.1/2/2014: just bought the ODC10-MDW and love it. Far better than the RAB I had... which btw failed 3 weeks in and kept the lights on all the time no matter how low the sensitivity was set. The dual technology is great. I was even having false set offs with this because of heat movement in my basement. So I lowered the IR sensitivity and raise the US sensitivity and it's perfect with no false set offs anymore. The only caveat is 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 an 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 it would annoy.
