What is a Humidity Sensor Switch?
A humidity sensor switch consists of a patented switch that detects and measures your room’s air or moisture level. After detecting humidity, it activates the exhaust fan to reduce the level of moisture. As a result, the growth of mold and mildew gets decreased to provide a comfy environment.
The great thing is, this device runs until the humidity drops below the predetermined relative humidity % setting. Suppose your family is forgetful about turning off the bathroom exhaust fan. In that case, a moisture sensing switch is a cost-effective and great way to remove moisture from your home, office, or bath.

The automatic turn on/off is an impressive feature of a humid exhaust fan switch. Due to this feature, when moisture increases in your bathroom, the switch turns on itself and activates the exhaust fan. So, you don’t need to remember to turn the exhaust fan on.
This feature is ideal if you have a toddler who frequently forgets to turn the fan on or residents in the rental property who are less careful about controlling the moisture. Fixtures and fittings get penetrated by damp air, even rusting water pipes and metal items.
Forgetting to shut off the exhaust fan is as bad as not shutting it on. How many times have you taken a bath and gone to work without turning the exhaust fan off? Ever imagined the electric cost?
It is a waste of electricity. It also absorbs warm and cooled air from your home, expelling it outside. This is similar to putting on some heating and opening a few windows of your home throughout the day.
So, a humid fan sensor performs to reduce heat build-up. At the same time, it helps you to utilize electricity at its best.
Saves Damage Repair Cost: As stated earlier, when humidity increases in the bathroom, it damages the wall and floor. In order to repair the damages, you will have to spend a lot of money. But if a humidity controller is installed in your bathroom, damages can be prevented. Thus, the repair cost will be saved.
The switch mounted in the fan guarantees that the level of humidity in your bath is within the safe range.
No Manual Control Required
Using a humid switch with a bath fan is convenient because you don’t need to operate it manually. As soon as it detects a humid level, it shuts on and off automatically.

What to Look for When Buying a Humidity Sensor Switch for Your Home or Office?
Maintaining the right humidity level is significantly crucial. The high humidity level will lead you to potential health risks. Not only this, your bathroom wall and floor will get damaged if you don’t control the moisture level.
So, you should buy the best product for your home use. Here we discussed a few factors which will help you in buying the best-suited product.
The accuracy of a humidity sensor switch is the most crucial factor. Unfortunately, no moisture sensing switches are 100% accurate in terms of measuring moisture. You should not expect 100% accuracy; there will always be an error margin of 3% – 4%. It is advisable not to buy a device that has more than a 4% error margin.
Since the device performs depending on a room’s moisture level, it has to be accurate in measuring the moisture.
If your bathroom moisture level is high, but the device cannot detect it and send a signal to the exhaust fan, then there is no point in installing a humidity controller. At the same time, if the device runs for a more extended period once the moisture level goes down, the unnecessary operation will increase your electric bill.
So, there is no choice except to buy an accurate and efficient humidity sensor switch for your resident.
Will you buy a device that is challenging to work with? Obviously, your answer will be NO. Always look for an easy-to-work and operate humidity sensor switch. We all want comfort in the house, and a flexible sensor will ensure relaxed and enjoyable shower time.
Generally, most adjustable humid switches perform automatically. They sense the pre-defined humidity level of a room and turn the exhaust fan for a specific period. Once the moisture level is reduced to a certain level, they stop working.
However, some models offer both automatic and manual configurations.
Many humidity controllers are tech-savvy. Now you will find an App, remote, and even voice-controlled adjustable humidity switch, which will allow you to control the device anytime and anywhere with ease.
When installing, some bath fan timer switches need a neutral wire.
So check whether your bath exhaust wall switch has a neutral wire. It is mandatory to install one if a neutral wire is unavailable.
If you live in an old house, the chance of having a neutral wire installed in the bath wall switch is less.
Remember, you will require a professional’s help to install a neutral wire. Don’t try to take it as a DIY task if you are unknown about different terms of electricity.
LED Indicator Lights
You will find LED indicator lights in most timer switches. This is a handy feature because you will be able to know if you set the timer correctly. Moreover, LED indicator lights to help you set the timer switches at the correct settings in low light conditions.
However, this is an additional feature that will give you an extra benefit.
Measurement range is another consideration that you should look at when buying the best humidity fan switch.
However, full humidity (0%-100%RH) measurements are not mandatory for temperature and humidity measurement and control of a room.
A standard humidity sensor switches temperature control range is -40 ~ 100℃, the display range of humidity is 5 ~ 99.0%RH. Check the specifications of your selected sensor to learn the measurement range.
Whatever model you choose, make sure it meets your requirements.
Along with the above considerations, you should look for the answer to the below questions.
Do You Prefer Fewer or More Settings?
Some models of bath fan switches come with only 2 buttons: ON/OFF and timer settings. At the same time, some others consist of more than 2 buttons.
If you prefer to work with simple settings, go with a sensor switch of 2 buttons.
How long do you want the timer to work for?
Some customers prefer less timers that last 30 minutes after a bath. On the other hand, others want a 12-hour timer that performs for a whole day.
Before buying any of them, you should get the answer to this question.
Button or Twist Timers – Which one to Choose?
Humidity sensor switches can be a button or twisted feature. All enlisted sensors in this list are button-featured; that doesn’t mean we should overlook the twist featured sensors.
However, both options are easy to use. But twisted featured sensors have a disadvantage. The adjustment can be changed if it receives a simple touch. On the other side, button featured sensors will allow you to set the time precisely.
Will You Be Pairing the Lights as Well?
Most timers can sync with fans, while others are suitable for light also. You can pair them together or decide to choose the fan-only option.
Before investing money, it is important to know your requirement. It would be best if you considered whether you need both fan and light.
As you can understand, there are lots of considerations that need to be kept in mind before making a buying decision. After you find the answer to your questions, you will be able to buy the best humidity sensor switch for your bathroom.
All moisture sensor’s functionalities are quite the same, but minor differences can be a big difference in the long run. As you invest valuable money, time, and effort, it would be best to buy the best product. Remember not to buy an inferior device because your money will be wasted.

How Does It Help to Control the Humidity of a Room?
Usually, you can operate a humidity sensor switch using 3 different operation modes. Each mode is designed to give you a relaxed time in the room.
Automatic Humidity Control Mode
Upon sensing the excess humidity, this mode automatically turns the bath fan on. It continuously monitors the humidity level and allows the bath exhaust fan to operate to reduce moisture. Once the water comes to a comfortable level, the sensor turns the fan off.
You need to keep in mind that, in automatic mode, a humid day won’t qualify as an event itself.
Manual Operation Mode
When you need to use the ventilation fan immediately, simply press or twist the fan icon of the humidity controller. This will let you turn the fan ON/OFF manually.
The automatic operation gets overridden by manual operation. Let’s say, after pressing the fan icon to pledge the manual system, the fan continues to run, even if the time is out. A user can set the timer adjustment to different intervals. Most humidity sensor switches allow its user to set the timer between 10/20/30 and 45 minutes.
However, don’t think that when the sensor performs in manual mode, it stops detecting humidity levels. It senses the level of moisture in manual mode as well, and when it detects the decrease of humidity level, the LED light starts blinking.
In the opposite case, this is true if you turn the fan off manually, but if the sensor detects that the fan needs to continue due to humidity, the LED light will flash to warn the user.
Air Cycle Mode
A bath exhaust fan turns on automatically for a specific period when air cycle mode is applied. Then the cycle repeats hourly.
This feature is significant for the areas where periodic or continuous ventilation is necessary, like laundry rooms, home spas, basement, etc.
Air cycle mode doesn’t get activated by the humidity range; it is intended for regular ventilation to help keep a house fresh from stale air.
Whether you choose to select Automatic, Manual, or Air cycle mode, the outcome will be best if you follow the below points meticulously.
- When the humidity sensor switch is turned on, keep the windows and door closed. If you keep them open, the device will be unable to detect subtle changes in the humidity.
- The sensor will not measure the tub/shower steam if the shower ceiling height is more than 8’. If your room or shower is large, install the sensor closer to the source of moisture or vapor.
- Season change may affect the sensor’s operation since the quality of ambient air changes. Adjust the sensitivity and humidity dial accordingly.
How to Use it for Longevity?
Humidity sensing switches can malfunction if they are not appropriately maintained. The proper using procedure will ensure a long lifespan of the device.
Follow the below using procedure to use it for longevity.
- The humidity sensor and fan control have 3 settings that can be adjusted. 3 settings are Sensitivity, Time adjustment, and Air cycle mode.
- Humidity levels can change based on a variety of reasons, including the change of seasons. To avoid the false activation of the fan, you can adjust the ambient humidity sensitivity. Turn the dial clockwise. It will enhance the sensitivity, so the device will respond faster to lower levels of humidity. On the other hand, if you turn the dial clockwise, the sensitivity for higher humidity levels will decrease. It can reduce the false activation of the fan.
- The time adjustment allows you to set the length of time you want the fan to remain on once activated. A sensor has time adjustment settings of 3 intervals: 10, 20, and 30 minutes. If you are using the humidity sensor for periodic ventilation in damp basements or home spas, rotate the humidistat dial clockwise to the air cycle mode. This setting will automatically turn the fan on for a set period every hour.
- You will then need to adjust the time adjustment dial to set the time, for example, 20 minutes on, 40 minutes off, each hour. This dial also controls the humidistat set point, which is the minimum humidity level that must be present before the sensor will turn on the fan. For instance, if the humidity set point is set at 50 and the relative humidity level in the room is 30, the device will not turn the fan on until the level is above 50. The humidistat dial is factory set in the “off” position when you receive it when appropriate for most applications.
- Ensure following the above operating procedure meticulously. You will get many years of efficient performance from the device.
What is the Ideal Setting for a Humidity Sensor Switch?
The humidity level in your bath will be determined based on the seasonal change and fluctuations of the outdoor temperature.
Follow the below chart of the ideal setting for a humidity sensor switch.
Outdoor Temp (F) Indoor Humidity Level (%)
50° + 45 (Max)
25° – 50° 40 (Max)
0° – 25° 30 – 40 (Max)
-20° – 0° 20 – 30 (Max)
