NPN Output Non Contact Water Level Detector XKC-Y25-NPN for Water Tank or Pipe Surface to Know Its Inner Liquid Level Sensor

Descrizione

The principle of the non-contact sensor is that it can convert the changed capacitance into a certain amount of electrical signal change, and then a certain algorithm detects and judges the degree of the change. When the change exceeds a certain threshold, The liquid level is considered to have reached the sensing point.
