Many manufacturers in the need for water level detection, will use the water level sensor, but some because of the material and structure, the water tank can not open holes, this kind of situation can be used capacitive water level sensor to detect.
Capacitive water level sensor is to convert the liquid level change into the signal output, which can quickly and accurately detect the water or no water state without contacting the liquid. Suitable for plastic, glass and other insulating containers, it should be noted that in the use of capacitive water level sensor, there should be no metal or magnetic field interference around.
