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.
The water 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 etc.
(The products to detect the amount of water or oil)

Mounting the sensor in a specific location inside the toilet seat above the man’s skin is the body’s capacitive touch is a way to detect and recognize. Application of capacitive touch sensor products on the smart phone looks like hand look at the way that if you touch is detected. Bidet current production of nearly 100 percent is using with this approach.
