The water level sensor product to recognize the value of the capacitance is changed by the water that was used to adjust the amount of water.
Thewater level sensor is divided into direct and indirect ways depend on the water contact with the sensor area or not.
Application
Water purifiers, Humidifiers, Boilers, Hot mats and etc.
(The products to detect the amount of water or oil)
