XKC-Y28B 5V 12V 24V Intelligent Non Contact Capacitive Style Pipe Water Leakage Detector Smart Water Leak Sensor

1st. Overview 

The water immersion sensor is a simple-to-operate liquid leakage monitoring device that can detect the moment of water leakage and issue an alarm in time. Water immersion sensor can effectively replace manual inspection, monitor water leakage in all areas with water sources such as rainwater leakage, water pipes, etc., and can conduct real-time monitoring and early warning of hidden water leakage. Water immersion sensors are mainly used in places with water requirements, such as computer rooms, power distribution rooms, data center rooms, communication rooms, power stations, intelligent buildings, warehouses, garages, factories, archives and other places.

3rd. working principle The intelligent non-contact liquid level sensor uses the inductive capacitance of water to detect whether there is liquid. When there is no liquid close to the sensor, the sensor has a certain static capacitance to the ground due to the distributed capacitance on the sensor. When the liquid level slowly rises and approaches the sensor, the parasitic capacitance of the liquid will be coupled to this static capacitance, making the capacitance value of the sensor larger, and the changed capacitance signal is then input to the control IC for signal conversion. The capacitance is converted into a change of a certain electrical signal, and then a certain algorithm is used to detect and judge the degree of this change. When the change exceeds a certain threshold, it is considered that the liquid level has reached the sensing point.
