To breathe and live healthy all we need is a clean, fresh and humid air around us.
When the temperature or climate turns to be extremely vulnerable, it becomes important for you to ensure that humidity levels are maintained at a certain level which is most comfortable and healthy.
If your home lacks proper humidity levels, it is highly recommended to install a good room humidifier to increase the level of humidity.
Along with a good air humidifier, installing a Humidistat device to monitor and control the relative humidity levels, is also very important.
If you want to control the moisture levels inside your home in an automated way, installing a humidistat is an ultimate solution.
You can install these devices along with your humidifier for controlling and maintaining the appropriate levels without worrying about the weather conditions and your family’s health.

What Is A Humidistat?
Humidistat is a small gadget that can be incorporated and fitted along with a humidifier without many efforts.
It is usually made of two components – sensing element and relay amplifier.
The sensing element is made to fit into a flat plate and contains metal conductors.
The relay amplifier is attached to the sensing unit and functions to read the signals send out by the sensing elements.
Once this is installed, the humidifier can get an actual measure of relative humidity levels to control it in a better way.
Humidistat is actually beneficial when it becomes important to maintain a particular desired humidity level, no matter what the outdoor weather and environmental conditions are.
For example certain rooms are more sensitive towards humidity and may even result in the formation of mildew.
In case you wish to control the humidity levels of your basement or bathroom then you can do so by easily fitting a humidistat to the ventilation area.
How Does A Humidistat Work?
Humidistat (also called hygrostat) is used to adjust the valves, dampers or other switches of the HVAC system.
It closes down a set of electrical contacts, when the humidity levels drop to certain point, thereby turning on the humidifier to ensure an effective management of humidity in the atmosphere.
Other than whole house humidifiers that are installed into your HVAC system or with your air conditioner, humidistats are also used in stand alone humidifier or dehumidifiers.
These often comes with an easy to use control knob.
Presently digital humidistat are also getting much popular in which desired humidity levels can be easily set/programmed.
These help to get real time update about the level of humidity in a specific location or room.
Depending on the readings generated by a digital humidistat, the humidifier is then put to use.
Humidistat: How it works?
Humidistat working principle usually employs a simple working pattern.
The conductor sets that are mounted on the sensing element will face an electrical resistance once there is a fall or variations in the moisture content.
The alternative metal conductors can eventually predict the quantity of electrical resistance by taking into account the relative humidity. The relay amplifier will then measure the resistance.
If the resistance has not reached the required levels, then the humidifier with humidistat is automatically turned on.
And in case electrical resistance has already reached an optimum level then the humidifier is simply turned off.
Humidistat vs. Hygrometer: What Is the Difference?
Humidistat is many times confused with Hygrometer and the two terms are often used interchangeably in place of one another.
It is therefore important to know about the basic difference between the both, before you use one or both of them for maintaining proper humidity.
✅ Hygrometer is an instrument which is used to measure or monitor the humidity levels in the atmosphere.
Its only function is to provide a digital or manual reading of the moisture level inside the room.
✅ Humidistat on the other hand is a device which is built into an appliance used to control the humidity levels of the room or whole house.
These are usually a built-in controlling device installed with/into an appliance to maintain the desired humidity levels automatically.
While differentiating between the both, it is to be remembered that a hygrometer can be used for to know whether or not you need a humidifier or a dehumidifier in your home.
Humidistat on the other hand, when combined with a humidifier or a dehumidifier helps in controlling the levels of moisture in your home to keep it at a desired level.
Humidistat vs. Dehumidistat: What Is the Difference?
Although a dehumidistat works similar to a humidistat, instead of closing the electrical contacts, it opens them up as soon as the humidity levels drops to a certain point.
When the relative humidity in a room increases, the electrical contacts gets closed and a dehumidistat starts working to lower down the room humidity by removing the extra humidity from the air.
Unlike humidistat, dehumidistat is also used to control the ventilation of the space, which can be controlled easily with a dial knob or via digital controls.
Humidistat vs. Thermostat: What Is the Difference?
While a Thermostat and Humidistat may sound to be a similar device to many, there is major basic difference between them.
Unlike humidistat switch, the main function of a thermostat is to monitor and control the temperature of a room (instead of humidity).
Usually attached with HVAC, thermostats are considered as a brain of these systems which not only turns them on and off as required but also helps in controlling/maintaining the desired level of temperature inside your home.
Programmable thermostats are presently more common as these are energy efficient to help regulate temperature in your home throughout the day as well as night.
These are adjustably designed to change the indoor temperature according to your programmed settings that takes effect at different time intervals.
Overall, installing a good humidistat unit OR a humidifier with built-in humidistat is surely a great way to control the humidity in your rooms all year long.
Although these devices can cost you bit more, these are worth investing as not having it can lead to problems like too low humidity OR excessively high humidity.
Both of these can cause various health issues if left uncontrolled for long.
Do not ignore adding it, if you want to give your family members the best health via optimum humidity levels inside your home or office.
