摘要
A 24-hour incontinence detection system contains a conductivity sensor being a passive device and is disposed in a vicinity of where a leak is most likely to occur. A liquid leak detection circuit is connected to the conductivity sensor and receives a resistance value sensed by the conductivity sensor. A Bluetooth transmitter is connected to the liquid detection circuit. An alarm receives a signal from the Bluetooth transmitter. The signal is representative of the output from the liquid leak detection circuit. The liquid leak detection circuit activates the alarm in dependence on the resistance value of the conductivity sensor.
