An electronic humidistat works by measuring capacitance of an air gap capacitor, or the resistance of hygroscopic salt, which absorbs water from the air. When measuring humidity against a set point, a power amplifier operates a relay.
In the capacitance type of sensor, the dielectric is the air in between two electrodes. The dielectric value, and therefore capacitance, will change according to the amount of water vapor contained in air.
A Mechanical Humidistat uses a material which changes size as it absorbs water, such animal hair, some plastics, or cellulosics, to move a mechanical switch.
For applications such as inside buildings, the temperature is stable enough that the conversion from absolute humidity to relative humidity is fairly uniform. Electronic controls can easily do temperature compensation for a wider and more accurate range of measurement.

What is the difference between a thermostat and humidistat?
A thermostat is a device that regulates temperature by turning heating or cooling systems on and off. A humidistat, on the other hand, measures and controls humidity levels in the air. While a thermostat focuses on temperature control, a humidistat focuses on humidity control.
How does adding humidity to the air in a residents affect the thermostat settling?
To answer your question as it is written: It has no Effect on the setting of the thermostat. If the stat is set at 72* and you add humidity, the stat is still set at 72*. Assuming you are really asking what the reaction of the stat will be, there will be no reaction. Humidity is latent heat measured by a humidistat, a thermostat can only measure and react to changes in sensible heat.
What are the types of mechanical work?
The types of mechanical work include static work, dynamic work, and intensive work. Static work refers to work done without motion, dynamic work involves movement, and intensive work focuses on the internal energy changes within a system.
How does input work and out put work affect the efficiency of a simple machine?
Input work is the work done on a machine, while output work is the work done by the machine. Efficiency of a simple machine is calculated as the ratio of output work to input work. The efficiency of a simple machine is high when the output work is close to the input work, indicating that the machine is converting most of the input work into useful output work.
What formula relates work and power?
The formula that relates work and power is: Power = Work / Time. Power is the rate at which work is done, which is the amount of work done divided by the time it takes to do that work.
With ac on do you also need to keep the humidistat on?
No you don't need the humidstat on as this defeats the purpose of the AC doing its work.
What is the difference between a thermostat and humidistat?

How does a humidistat work with air conditioning?
An electronic humidistat works by measuring capacitance of an air gap capacitor. In this type of sensor, as air flows in between two electrodes, the capacitance between two plates will change according to the RH contained in air.
What What is the difference between a humidistat and a dehumidistat?
The difference is the relay operation.Normally opened or normally closed.If you add an external spdt relay,you could have a humidistat/dehumidistat.
How can humidity be checked in the home?
With a temp/rh probe barring that take a humidistat and turn dial when it clicks from closing circuit note the setting and that is humidity surrounding humidistat
How can you turn on your central heat when you have a humidistat?
Not sure how it works, but it seems that you need to raise the humidistat to make the heat go on. Just raising the thermostat doesn't turn on the heater. Type your answer here...
What is the purpose of a humidistat?
A humidistat is a device used to control the operation of space conditioning systems such as air conditioners, dehumidifiers and humidifiers. When used with an air conditioner, for example, the humidistat cycles the unit on and off based on humidity rather than temperature as provided with a regular thermostat. A humidistat set at 70 percent relative humidity, for instance, will cycle the air conditioner on when relative humidity reaches 70 percent or above, even if the thermostat setting does not call for cooling.
What is the role of a humidistat in controlling the humidity levels of a humidifier?
A humidistat is a device that measures the humidity levels in the air. It is used in a humidifier to control the amount of moisture released into the air. When the humidity levels reach a certain point set by the user, the humidistat signals the humidifier to either turn on or off to maintain the desired humidity level.
Where can you buy a humidistat?
I bought mine from a shop reptile shop but you can get them off of the internet
What setting should a humidistat be set to?
My dehumidistat says to set the temperature to 70 degrees.
What setting should a humidistat be set?
My dehumidistat says to set the temperature to 70 degrees.
What would cause an air conditioner to start suddenly even when the thermostat is off?
System could have a humidistat installed...
