With an improved air freshener option, it can not only contain a small amount of bacteria, and infections, but also have a moisture-wicking ability. My only concern is that its not at all environmentally friendly so I will be thinking carefully about whether to carry on getting the refills.

You now have access to the digitized sensor output at the outer pin of the white connector and a smaller module. It looks to be marked PB775B01M20-R Revision 0, dated 3rd August 2010 (a while back) but made Week 38 of 2013. If you look at the removed switch's pads you can see that 6 have been selected and the outer 4 of the six enlarged. It seems the internal section of the unit is marked much the same as the outside, with FCC and CE approval markings. Not sure I like the smell, its really strong, and its quite annoying to get a full burst of spray when you walk past.

There are three resistance jumper settings on the left – these are fixed on this model, but is likely to set the lock-out time, as the other model they have on their web page can be configured for 15-minute, 20-minute and 30-minute lock-outs. Removing the middle reduction gear “breaks” the chain of processes, and allows you to see how the sector-shaped gear works.

Downfall would what to replace batteries all the time and make sure you put it where you don't get sprayed in the face as you walk by.The motion sensor air freshener dispenser is a popular choice for its ease of use and ability to provide a continuous scent experience. It is a battery operated device with a built-in motion sensor and concentrated mini-aerosol spray refill. The Glade air freshener uses a light level (shadow) detector and a motor and gear train to depress the canister nozzle and dispense the fragrance. I was sent this to review but I wouldn't purchase it again for our home, I think if you have it in a small space it may work well but the smell seems to get lost in our house so unless you're standing right near it the smell is very faint. The battery-operated holder conserves refills using motion sensor technology, motion activated releasing a burst of home fragrance when you pass by or turn on the light.
