XKC-Y25-V Non-contact Digital Water / Liquid Level Sensor

The XKC-Y25-V sensor detects the level of a liquid without contact through the wall of the container, it measures capacitively. This makes it suitable for toxic substances, strong acids and alkalis in closed containers, even under pressure. Metal containers are not suitable, otherwise the sensor makes no special demands on the liquid.

Important: In the high state, the output delivers the supply voltage. For an Arduino UNO, supply the sensor with 5 V. On 3.3 V boards such as the ESP32, use a level shifter or voltage divider.
