Automatic Humidity Control Systems: Comprehensive Overview


Automatic Humidity Control Systems
Automatic humidity control is important in your home as it can help protect your belongings and your health.

Having an automatic humidity control system to control the relative humidity in your home or workplace is important for many reasons. Depending on your requirements, there are different humidity controller solutions available.

Whether you are trying to control:

  • moisture in the living and bedrooms of your home,
  • kitchen and bathroom humidity, or
  • more specialized needs such as for greenhouses, museums, or other commercial applications,

… here we discuss some of the options available to you.

But first, here is some of the background information that you may find useful…

What Is Relative Humidity?

You have very likely heard the term ‘relative humidity’ used in relation to weather and air quality information. Relative humidity (RH) is a measurement that reveals the amount of moisture being held in the air at a specific time. If the RH is 100%, this means the air cannot hold any more water (ie. it is saturated).

For a more detailed explanation of relative humidity, click here.

The higher the moisture content, the more humid the air becomes. For many with respiratory issues, high humidity makes the air difficult to breathe. Also, with all that moisture a humid room or house can be a perfect breeding ground for mold and mildew to develop and grow.

Bacteria growth in high humidity conditions is not only bad for our health; it is not good for a home. Wood, in particular, is susceptible to damage from excess moisture. Condensation can also form which can result in water staining, wallpaper peeling, and insect infestation.

Introduction to Automatic Humidity Control Systems

Automatic humidity control systems are innovative technological solutions designed to regulate and manage indoor humidity levels seamlessly. In environments where humidity can significantly impact comfort, health, and even the structural integrity of buildings, these systems prove to be indispensable.

Definition and Purpose

At their core, automatic humidity control systems are sophisticated devices that monitor the humidity levels within a space and adjust them as needed to maintain a predefined optimal range. They achieve this through a combination of sensors, actuators, and control algorithms. These systems can be integrated into HVAC (Heating, Ventilation, and Air Conditioning) systems or operated as standalone units, depending on the specific requirements of the setting.

The primary purpose of these systems is to ensure that indoor humidity remains within a balanced and health-supportive range. High humidity levels can lead to issues such as mold growth, allergen proliferation, and discomfort. On the other hand, excessively low humidity can result in dry skin, respiratory problems, and even damage to wooden furniture and musical instruments. Automatic humidity control systems mitigate these problems by consistently adjusting the humidity levels to create an environment that is conducive to human health, comfort, and the preservation of valuable items.

Benefits of Using Automatic Humidity Control Systems

  1. Health and Comfort: Maintaining optimal humidity levels contributes to a healthier indoor environment. By preventing excess moisture and mold growth, these systems help reduce allergens and improve air quality. Additionally, maintaining comfortable humidity levels reduces skin dryness and respiratory irritation.
  2. Preservation of Assets: Automatic humidity control systems are particularly beneficial for preserving valuable possessions. For instance, in museums, libraries, and archives, maintaining stable humidity helps protect artwork, rare books, manuscripts, and historical artifacts from deterioration due to fluctuating moisture levels.
  3. Energy Efficiency: These systems optimize humidity levels while minimizing energy consumption. They ensure that humidification or dehumidification processes are only activated when necessary, leading to energy savings and reduced utility costs.
  4. Structural Integrity: In homes and commercial buildings, excessive humidity can lead to structural issues like warping of wooden components and corrosion of metal fixtures. By controlling humidity levels, these systems contribute to the longevity of the building’s materials.
  5. Automation and Convenience: Automatic humidity control eliminates the need for manual adjustments. Once the desired humidity range is set, the system operates autonomously, freeing occupants from the hassle of constant monitoring and adjustments.
  6. Customization: Different environments require different humidity levels. These systems offer customization options, allowing users to set humidity targets based on their specific needs, whether it’s a wine cellar, a data center, or a healthcare facility.

Types of Humidity Control Systems For Your Home

Humidity can be controlled in several ways with different types of appliances. An air conditioner will help with temperature regulation and can help to reduce humidity. However, the actual moisture content in that air can be controlled more precisely by other means. Different methods include:

  • Using either a humidifier or dehumidifier, with a built-in humidity sensor,
  • Using a moisture sensor switch to accurately control the humidity levels, or
  • Using a humidistat-controlled extractor fan. This is often the best solution for controlling kitchen and bathroom humidity and where moisture buildup can be severe.

Using Humidifiers Or Dehumidifiers

A humidifier is used to increase the humidity in a home or room. There are several different methods used to achieve this but in a residential setting, the most common involve evaporation or misting element. Either will add moisture to the air raising the level of humidity.

For a look at our picks of some of the best humidifiers on the market, click here.

A dehumidifier does the opposite of a humidifier. When the humidity level is too high a dehumidifier can extract the excess moisture. It does this by collecting condensation on coils that air passes over. The water is then stored in a reservoir to be removed when full or near capacity, or pumped directly into a near drain.

For some people that use a humidifier or dehumidifier, these units can do a good job of keeping the humidity levels constant, but they run even when you are not at home (eg. when you are at work). A solution is to install a timer (eg. Hydrofarm TM01715D 7-Day Digital Program Timer), which you can program to turn on a ½ hour before you are due to arrive home. This means that you will not waste excess energy, and the air in your home will be at the right RH level when you get home.

Using A Moisture Sensor Switch

As the name suggests, this unit contains a sensor that monitors the moisture levels in the air. You can then hook this up to a humidifier, dehumidifier, or extractor fan to accurately control humidity or extract moist air.

One problem with using humidifiers and dehumidifiers is that the humidity sensor is built into the unit. As such, they can affect the air in the immediate vicinity and can cause the unit to turn on or off when air further away is not at the correct RH. This can be overcome by using a sensor switch that is separate from the humidifier or dehumidifier.

See more about this option in our review of the WILLHI Air Humidity Controller, and the Leviton Humidity Sensor below.

Using A Humidistat Controlled Extractor Fan

This type of unit combines a sensor and fan into 1 unit. This is a neat solution to automatically switch on when required to control kitchen and bathroom humidity.

Components and Working Mechanism

Automatic humidity control systems are intricate setups that rely on a combination of specialized components working harmoniously to regulate indoor humidity levels. Understanding the key components and their collaborative functionality provides insight into the complexity of these systems.


1. Humidity Sensors: At the heart of automatic humidity control systems are humidity sensors, also known as hygrometers. These sensors continuously measure the moisture content in the air. They can be based on various technologies such as capacitive, resistive, or thermal sensing. The sensor gathers data on the current humidity level and relays this information to the control unit.

2. Control Unit: The control unit serves as the brain of the system. It receives the data from the humidity sensors and compares it to the desired humidity setpoint. This setpoint is typically user-defined based on the specific requirements of the environment. The control unit processes the data and determines whether humidification, dehumidification or no action is needed.

3. Actuators: Actuators are responsible for implementing the required actions based on the control unit’s decision. There are two primary types of actuators in automatic humidity control systems:

  • Humidifiers: When the humidity level is too low, the control unit activates humidifiers. These devices release moisture into the air, raising the humidity to the desired level. Humidifiers can use methods like evaporative, ultrasonic, or steam-based humidification.
  • Dehumidifiers: In cases of excess humidity, dehumidifiers come into play. They work to remove moisture from the air, lowering the humidity to the desired level. Dehumidification methods include refrigeration-based, desiccant, or thermoelectric dehumidifiers.

4. Feedback Loop: Automatic humidity control systems operate in a feedback loop. As the humidity sensors continuously monitor the indoor humidity, they transmit real-time data to the control unit. If the measured humidity deviates from the setpoint, the control unit commands the appropriate action through the actuators. Once the desired humidity level is achieved, the system adjusts its actions accordingly, maintaining a dynamic equilibrium.

5. User Interface: Modern automatic humidity control systems often come with a user interface that allows occupants to set the desired humidity level, view real-time humidity readings, and even schedule operation times. This interface provides users with control and visibility into the system’s functionality.

Working Mechanism

  1. Data Collection: Humidity sensors detect the current humidity level and transmit this data to the control unit.
  2. Comparison and Decision: The control unit compares the measured humidity to the desired setpoint. If a deviation is detected, the control unit determines whether to activate humidification or dehumidification.
  3. Action Implementation: Based on the control unit’s decision, the appropriate actuator (humidifier or dehumidifier) is activated to introduce moisture or remove moisture from the air.
  4. Continuous Monitoring: Humidity sensors continue to monitor the indoor environment, ensuring that the desired humidity level is maintained.
  5. Dynamic Adjustment: As the humidity level approaches the desired setpoint, the control unit adjusts the operation of the actuators to prevent overshooting or undershooting the target humidity.

What Should The Humidity Level Be In My House?

automatic humidity control system

As a guide, the humidity level in your home should fall between 40 and 50%. However, because of fluctuations in temperature, individual rooms, storage spaces, and attics can have different levels. It is actually much easier to explain what your home humidity level should not be.

If the relative humidity falls below 30% it is considered to be too dry. At this level, you may experience skin irritations such as cracked skin, itchy spots, and rashes. It will also dry your respiratory system causing sore throats, coughing and nosebleeds, and even headaches.

When the humidity is above 50% it can create a whole different set of problems; from health issues, to damage to furniture, to promoting bacteria growth. However, it is actually quite easy to monitor and correct the humidity level in your home and in individual rooms and areas.

How Do You Measure Humidity In Your Home?

A variety of tools are available for assessing humidity levels within a room or home. These tools fall into distinct categories: hygrometers, which exclusively measure humidity, and combination devices that offer both thermometer and humidity readings. This range of options allows you to choose the tool that best suits your specific needs for monitoring humidity levels.

Analog-style hygrometers are generally accurate to within 10% (plus or minus) of the actual level. They are sufficient for many applications and will give you a good idea of the approximate amount of moisture content in the air in your home, basement, or crawlspace.

The most accurate measuring device is a digital hygrometer. These are accurate to within about 2.5% plus or minus the actual relative humidity. If you have collectibles or items requiring certain humidity levels, this is no better monitor to choose from.

Installing An Automatic Humidity Control System

You can easily buy an automatic humidity control system and get it installed in your home. Some important things to consider include:

Sensor Location

If the unit contains a remote sensor, it is important to consider the mounting location. As it will be triggering the fan to ventilate the area it is located in, the sensor needs to be away from places that can send false signals to it which will start the fan when it is not required to operate.

Places to keep the sensor away from include doors, windows, heating apparatus, stoves, aquariums, and anything else that could incorrectly trigger the sensor. It should be placed in the center of a wall in order to operate properly.

When you measure the room in which you are installing the system, try to keep the sensor and fan as central as possible. However, the sensor and the fan require distance between them. The fan should be no closer than a few feet from the sensor or it can affect the readings it will receive.

Wireless Sensors

Some sensors available currently are wireless in design. This eliminates the need for plugging them in or running wires between the sensor and fan unit. In this case, the sensor still requires careful handling as well as careful positioning in order to function.

The sensor needs to be able to ‘talk’ to the fan so it can be attached to a wall or sit on a countertop. It can also be mounted to a piece of furniture that does not get moved around (like an entertainment unit). It needs to have a constant ‘connection’ with the fan wherever you place it.


Depending on the setup you go ahead with, your humidity controller may require professional installation from an expert such as an electrician. They will be able to hook up the new equipment and run wires within the walls if required.

If this is the case, you can still buy the extractor fan, moisture sensor switch, humidifier, or dehumidifier beforehand, and then simply get the professional to do the installation. This way, you have control over exactly what you get and don’t have to pay the markup that the installer may often charge.
