A moisture detector detects moisture in a closed environment. A microcontroller is connected to an elongated strip sensor, a spot sensor, or a combination of strip sensors and spot sensors. The elongated strip sensors have fabric substrate with parallel conductor strips. The spot sensors comprise point electrodes embedded in a substrate consisting of existing building material. The conductor strips and the point electrodes are connected to the microcontroller. The electrical resistance of the substrates vary based on the amount for moisture absorbed, and the microcontroller may be programmed to detect a threshold resistance indicative of the presence of moisture. Once moisture is detected, the microcontroller can provide various alarm functions and communication functions.
