The new Leviton Humidity Sensor and Fan Control automatically detect excess humidity in a room and activate the ventilation fan to reduce condensation. This helps to lessen the appearance of mold and mildew and provides a more comfortable environment. The sensor uses a microprocessor combined with state-of-the-art digital sensing technology to continuously monitor and manage humidity levels in areas of the home prone to condensation and mildew. It features user-friendly controls to adjust sensitivity, humidity level and time out settings. The sensor can replace a single pole switch and can be used with most bathroom or ventilation fans or fan/light combinations. It is designed to fit within a standard wall box and requires a neutral wire for operation.
Replaces a single pole switch for control of a ventilation fan or a fan/light combination
Meets cal green and CA title 24 requirements; sensor is equipped with user adjustable humidity range set points to set the minimum humidity level at which the fan will automatically operate
Automatic ventilation/air cycle mode for continuous operation with hourly pre-set time outs
Compatible with incandescent, LED, CFL and fluorescent lighting loads
Green LED functions as a status indicator (fan on/off, air cycle mode, manual override)
Use with existing or new ventilation fans up to 1/6 HP, 4 Amp
Installation was a breeze works exactly as advertised. Remember to adjust the timing and sensitivity settings to your situation.

I wanted a way to automatically control our bath fan so that it would run a minimum of 20 minutes (to exhaust all humidity out of the bath), then shut off automatically. I bought this switch and installed it myself. The installation was not difficult. I did have to adjust the humidity controls as is expected to get the settings right. That took a few tries but it was easy to do. The fan/light controller works as expected and is running the way I want it. I replaced a dual switch which controlled the light and the fan separately. This switch controls both and you cannot separately control the light or switch. Hopefully, Leviton someday will develop a way to do that. In the mean time, this product works well and I don't have to manuallly remember to turn off the fan. I would recommend the product to anyone wanting to automatically run a fan.

Great after a LOT of dialing in
I bought two of these switches for our full baths. I considered purchasing fans with built in humidity sensors instead, since humidity travels up. In the end I wanted the switching to happen at the wall in case the humidity sensor needed seasonal adjustments.
Installed the first switch in our master bath and left it on the factory settings - high sensitivity, automatic detection of humidity “events”. I left the front appearance plate and the cover for the switch adjustments off for several days in case we needed to access the adjustment dials. Ran the shower for a bit and the switch kicked the fan on - success!!
That night the fan kicked on probably a half dozen times while I was trying to sleep. Finally got fed up and flipped the breaker to turn it off. Spent the next day trying to get the sensitivity dialed in, but either the fan didn’t kick on during a shower OR it did but it also kicked on at other times.
At this point I was tempted to give up and pull the switch out. I persisted because 1) I’m kinda lazy and 2) my husband grew up without ever using a bathroom fan, has not successfully learned to use one as an adult, and has managed to ruin several fixtures in the bathroom by letting the steam build up until the walls begin to drip. I simply HAD to have something in place that would automate the process.
After the second day, it occurred to me that the “humidity event” sensor is looking for a sudden rapid rise in humidity. Here in a southeast summer the humidity is already so high that the steam from a shower doesn’t register as a significant change. From there, I made the appropriate adjustments to override the “event detection” mode.
I set the humidistat dial to a level just a bit higher than the average summer humidity in our house. This worked a lot better and from there I spent another couple of days making small adjustments to the sensitivity to get it dialed in just right.
After four days, I think I can claim I’ve successfully gotten this thing working right. It kicks on just before fog starts to occur at the tops of the mirrors and runs until the bathroom is defogged. It took a little bit of frustration but I couldn’t be happier now that it’s working.
If you’re considering this because it’s a neat gadget, it may not be worth your time. If you need a device that will make up for the fact that your family (or guests) were raised like wild animals, and you’re willing to spend a few days goofing around with the settings, I think you’re going to love this switch.
Photos: installed switch without the decorative plate or the adjustment cover installed. I opted for the Leviton screwless plates, so the mounting bracket is present here but not the finish plate. Amateur tip: map your circuit breakers - but ALSO write the breaker number on the back of the switch plate for a quick reference!!

Local code requires these to be installed in all bathroom remodels. Since the on/off function is integrated into the design, I mounted this in the 4' standard switch height position. This elevation is too low for steam to adequately activate the fan automatically. I installed a second one 6" from the ceiling to get proper automatic ventilation when the shower is active (see below). The wiring is configured in such a way that if either switch is active, the fan turns on. I strongly recommend this method. This requires a little extra electrical planning. Also, make sure the switch is 6' (horizontal) from the extent of shower/bath
Pros: Once the sensor was placed at the proper height above the floor, It turns on in time to automatically prevent bathroom fog-up. The connections are all the screw compression, so it works well with both solid and stranded wire (all 4 connections including ground). The switches can be safely installed in parallel.
Cons: There is a 5 second delay from the manual activation of the fan until it actually turns on. There are 3 adjustments that are confusing and not intuitive (e.g. time, sensitivity, and humidity). The access to the adjustment screws is not intuitively obvious. Read those instructions.

It works as it's supposed to. If you read the directions it's easy enough to program-I set mine to come on for 20 mins when I want to manually turn it on. It turns itself on when I take a shower-I do wish it would stay on a bit longer though-and yes I have it set to the highest sensitivity...
But here's my gripe-and I'm surprised I'm the only one to complain about this: When the unit is OFF-the green light is ON. When the unit is ON-the green light is OFF. I have 4 other (5 total) digital timer switches in this bathroom-and on every single one of the them LED indicator light is ON when you turn the switch on-makes sense, right? And when they power OFF, the LED indicator light goes OFF. This is the only switch I've ever seen where it operates the exact opposite of what would be considered common sense. I've had this thing for 6 months, and I still cannot get used to it! Leviton-please consider fixing this design flaw.
If you notice in the photo's I've attached, I have turned all the other switches ON-including this one. It is the ONLY one where the indicator light (located above the fan drawing) isn't on. In all photos it's the switch on the far right. I also included a photo with the switch OFF-and you'll notice the indicator light is ON!?!
I still recommend it though-it works as advertised. Maybe I'm too picky...

5 AMP HUMIDITY SENSOR FAN SPEED CONTROL, WHITE
I was looking forward & delighted to have it for my hall bathroom rather than to turn fan switch before & after my showers. My hall bathroom really needed automatically venting @ any time there was humidity. i had a handyman to install it for me but not accomplished it to get working. he retried 3 times, still not working. maybe defected? I was sooooo disappointed. I really wanted to have it automatically turning itself @ any time instead of to turn switch on. boo hoo

It does work, but it takes a while to get the settings right so that it doesn't turn on in the middle of the night when the house is being cooled and so it does turn on after taking a shower. Also, had to install it sideways since my bathroom light and fan switches are all in a 4-gang electrical box installed vertically.

Great fan control
This is the third Humidity sensor I have installed in the last month. It just makes sense for a bathroom fan to come on automatically. It's hard to get everyone in your household to turn the fan on when they have taken a bath or shower. This eliminates trying to get everyone on board to run it on. There are several settings that you can adjust on the unit. Like how long it runs, how much humidity it needs to sense before it turns I actually decided to use the preset factory settings. It is working just fine for me at their settings. I also like the feature that when someone stinks up the bathroom they can just touch the sensor and it will run for 10 min. or whatever you have it preset for. Wish my Home Depot carried these in the store, but I did have to order them online in order to get them. Shipping was really quick though, 2 days.
Now I don't have to remember to go turn off the bathroom fan iafter a shower (or remember to turn it on for that matter). I was always forgetting to turn off the fan in the bathroom after my morning shower. 8 hours later when I get home from work, it was still doing its job. When I found out I could get a fan sensor and timer my mind was blown.
The install is a little time consuming because most bathroom fan switches don't require a neutral wire connection, so you typically have to re-wire the switch box a bit. This is so the sensor always has power and can monitor the humidity level for changes. It's also deep, so you will spend some time squishing wires around.
Once installed it's great. You have a manual override, which is also timed so if you leave it running it will turn off after your preprogrammed configuration. I set mine between 10 and 20 minute marks, it can go for up to 60. You can also adjust or turn off the humidistat if you like. And it also comes with the ability to turn on-off at specific intervals if you have a room that needs constant ventilation like an attic.
As for usage; I have not had any false positives yet. The default setting for the humidistat seems to be a good option.
Why did I give it only 4 stars; it has 3 design choices that bug me. First you have to remove the faceplate and then gently pry the plastic switch button off the front to make adjustments. Sure you shouldn't have to make changes often but this is goofy and I don't want to break the plastic ears holding the switch plate to the front. The LED on the front, not everyone wants a light switch to glow. The push button is flimsy and gets caught on the switch faceplate cover from time to time, I'm not sure why I can disconnect it from the switch either, seems like another piece that can be broken with use.
All in all I am glad to have it and it indeed insures I don't have moisture in my bathroom.
Perfect addition to a bathroom with a humidity issue
Perfect addition to a bathroom with a humidity issue. This is a great way to eliminate moldy damp bathrooms.
Before showering, I push the fan button and let it run. When I come back later, the fan has automatically turned off and the bathroom is dry.
Installation was super easy. The provided instructions are well written and easy to follow with an understanding of basic electrical. It fits perfectly in a decora plate and blends in well
Perfect for people who have to run out of the house as soon as they finish showering !
