**Moisture Mapping** is a crucial aspect of building maintenance that involves identifying and mapping areas with excessive moisture levels. Moisture detection is essential for preventing structural damage, mold growth, and other health hazards. Several methods are employed to detect moisture, each with its advantages and limitations.

### How Does Moisture Detection Work?

Moisture detection methods utilize various principles to identify moisture presence. Some common techniques include:

– **Condensation Measurement:** Measures the amount of condensation on surfaces, indicating high moisture levels.
– **Electrical Resistance:** Moisture increases electrical conductivity, allowing sensors to detect its presence.
– **Capacitive Sensing:** Monitors changes in capacitance caused by moisture, providing an indication of its presence and severity.
– **Thermal Imaging:** Exploits temperature differences to detect moisture, as wet areas appear cooler or hotter than dry areas.
– **Infrared Sensing:** Utilizes infrared radiation to identify areas with unusual moisture levels, indicated by temperature fluctuations.
