Abstract: For moisture detection and prevention systems, the reduction or prevention of false positive and false negative alarms is of immense economic value. A method of discriminating the types of materials in contact with a capacitive detector can be easily implemented even for battery-powered devices and has already proven useful in testing in preventing false alarms, and discriminating various solutions.

Abstract: A heating device for volatizing materials contained in an impregnated pad has a housing including a chamber to receive an impregnated pad for heating, a battery contained in the housing, and a heater arrangement. The heater arrangement in one mode includes at least two heaters, a temperature sensor, and a controller, wherein the controller is configured to power the first heater based on a first temperature and then to power the second heater after the first temperature reaches a second temperature. In another mode, the heater arrangement has at least one heater, temperature sensor, and controller, wherein the controller is configured to provide battery power to the at least one heater to volatize materials in the impregnated pad. The housing has at least one opening to allow volatized materials from the impregnated pad to escape from the housing.

Abstract: A moisture sensor includes a circuit board and a plurality of circuits monitoring a plurality of moisture probes, wherein at least two sets of a plurality of probes are on the bottom of the sensor, one set in direct contact with the floor, a second set separated from the floor; a set of conductive pins that enable the body of the circuit board to be spaced from the floor to help any moisture accumulation beneath the sensor to evaporate, preventing mold growth; two sets of a plurality of probes along the edge of the sensor, such that when the sensor is installed edge on, these edge sensors will be in direct contact with the floor. The sensor transmits data periodically when sensed resistance is below a predetermined value.
