Humidity & Moisture

The difference between humidity and relative humidity is that humidity says how much water vapor is in the air, and relative humidity indicates the percentage of how much vapor in the air holds the maximum amount of water that is can hold (at a specific temperature). Moisture is far simpler, as it is most commonly used to describe the saturation of water in soil.


For many applications, readily-available humidity and moisture data is advantageous, especially those involving animals, plants and sensitive electronics. Here are some more ezeio humidity monitoring applications:

  • Air quality monitoring – for conference rooms, exhibit halls, museums.

  • Economizer control – monitor inside and outside air for selecting the optimal cooling mixture.

  • Greenhouses – control and monitor humidity for optimal growth conditions.

  • Weather stations – collect accurate humidity data over time from multiple sites.

  • Dew point monitoring/ASH control – limit fog build-up on refrigerator glass doors.

  • Irrigation monitoring – track soil moisture to control and record irrigation requirements.


There are several models of humidity sensors that work with ezeio controllers. Some are designed for harsh operating environments, others must be protected from direct exposure to water, some can be mounted on HVAC ducts or the wall, and most moisture sensors can be easily adapted to work with your ezeio controller too.
