## Description

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. Key Features Non-Contact Detection – Senses liquid level through container walls 4 Sensitivity Levels – Adjustable via onboard SET button Gravity Digital Interface – 3-pin plug-and-play connection Hazardous Liquid Safe – No contact with the liquid being measured Wide Container Compatibility – Works with non-metallic containers Specifications Chip: XKC-Y25-T12V Interface: Gravity digital (3-pin) Output: Digital high/low Ideal For Water tank level monitoring Chemical and hazardous liquid detection Aquarium and hydroponics systems Industrial process monitoring Package Contents 1× Liquid level sensor probe 1× Liquid level sensor adapter 1× Gravity digital 3-pin cable Resources Product wiki
