How do Humidistats work?
Humidistats are used in conjunction with humidifiers, air conditioners and dehumidifiers. They use a sensor element to detect moisture in the air and monitor its levels, they then control the device turning it on and off when needed. Using electrical resistance and metal conductors, a relay amplifier will measure resistance allowing the humidistat to determine whether to switch a device on or off to reach optimal levels.
