The non-contact liquid level detection sensor, as the name implies, detects the state change of the liquid level without touching the liquid. Capacitive liquid level sensor is a non-contact type, which is equipped with precision touch MCU, to determine whether the tank is short of water by sensing the difference in the capacitance value in water and the absence of water.
Capacitive liquid level sensor is more suitable for normal temperature environment, and the installation is also very convenient and simple. The sensor is close to the outer wall of the water tank container, which can be detected without debugging. Because of the principle of capacitive induction type, there can be no metal or magnetic field interference within 2cm around the sensor, which will cause the sensor to not function normally.
Capacitive liquid level sensor is small, sensitive and high precision, and can realize the function of water shortage alarm and full water power off.
