The Basic Operation Of A Humidity Controller

In many different industries, including in greenhouses and other types of operations, the use of a humidity controller is essential. These devices are very similar to a thermostat except they are designed to register and react to the humidity in the air and not the temperature.

However, there is a connection between temperature and humidity. As the temperature of air heats up or increases, the air becomes capable of holding more water vapor. This is something people experience on hot, humid summer days that is simply not duplicated when temperatures are lower at other times of the year.

Area to Monitor

All humidity controller models will be used for specific amounts of space or the area for the misting system. Most are designed as single zone controllers, but there are more extensive and sophisticated systems that are used to control multiple zones.

Each zone will have a sensor that detects the specific humidity in that area. This reading is then converted to an electronic signal that is sent to the main controller unit. If the data indicates the humidity is lower is than the pre-set range the controller turns on the misting system automatically.

When the reading from the remote sensor or the unit in a single zone system registers the humidity above the pre-set limit, the misting system is turned off. Systems can be very sophisticated with a range of different programmable features to manage a complete building, greenhouse or facility.

Complex Control

With the link between temperature and humidity, many of the humidity controller systems are designed to complete dual measurements. This allows easy control of both temperature and humidity from the same system.

Not only does this save the costs of having to install two sets of remote sensors and systems, but it also increases accuracy and efficiency, both important factors to consider.
