This article reviews the methods, principles, and performances of moisture measurement in building envelopes with a focus on continuous monitoring applications. It compiles an extensive list of closely related literature. Brief examples are presented to demonstrate measurement values and a presentation approach for measured electric-resistance data. Moisture measurement methods have various capabilities. Some methods can quantify moisture content for some building materials such as timber, while also providing comparative values or changes in wetness conditions for other building materials. Other methods are used to warn of excessive wetness conditions in the envelope, particularly in hidden or difficult-to-access areas. Reviewed methods are grouped according to the measurement principle: for example, resistance, voltage, and thermal-based methods. Resistance and voltage-based sensors are most suitable for continuous monitoring applications as they can be readily connected to a data logging system. Voltage-based methods such as the Sereda and printed circuit sensors are usually used to indicate time-of-wetness of surfaces. Their main weakness is durability, which can be quite short in outdoor applications. Resistance-based methods, such as moisture pins, Duff sensors, and ceramic sensors, are used to monitor changes in moisture level within materials as well as time-of-wetness of surfaces. These sensors are durable and can be fabricated in-house.
