Gravity: Non-contact Arduino Water / Liquid Level Sensor

A non-contact liquid level sensor that detects the presence of liquid through a container wall — no direct contact with the liquid required. Using advanced signal processing via the XKC-Y25-T12V chip, it works through most non-metallic containers including plastic, glass, and ceramic.

This makes it ideal for hazardous applications involving toxic substances, strong acids, strong alkalis, or pressurised containers. Four sensitivity levels are configurable via the onboard SET button. The included Gravity interface adapter provides plug-and-play compatibility with DFRobot Gravity expansion boards and Arduino.
