WATER INTRUSION AND LEAKAGE DETECTION IN ENVIRONMENTS WITH HIGH CONDENSATION

Abstract:
Many technical devices but also non-technical devices and objects are sensitive to water. Excessive amounts of water may lead to a damage or even malfunction of them. Water detection can thus be a useful tool for preventive maintenance, in particular in combination with wireless sensor nodes. In addition, with respect to warranty of technical devices, water detection also helps to identify if specified operation conditions have been violated. In both cases, it is important to achieve a high detection rate whereas false alarms should be avoided. A common source of false alarms is condensation due to changing environmental temperature. In this paper, we suggest a water detection sensor that has low sensitivity to condensation yet high sensitivity to leakage water. Due to low power consumption, it is well appropriate for wireless applications.
