This flexible capacitive liquid level sensor detects liquid through the wall of a non-conductive container, so it does not need to touch the liquid itself. It is designed for containers with a wall thickness of less than 5 mm, making it handy for sealed tanks, pipes and other setups where a contact probe is not ideal.
The thin flexible substrate has temperature-resistant and waterproof 3M adhesive tape on the back, so it can be attached directly to suitable container surfaces. It outputs a simple digital high/low signal, with a low output when liquid is detected.
The sensor uses a 3-pin DuPont connector and suits applications such as water tank detection, beverage machines, water pipe level detection and scientific experiment test tube level detection. A DFRobot product wiki is available, and the shipping list includes one Gravity non-contact capacitive flexible liquid level sensor.

Jargon buster
Plain-language definitions for the technical terms used above.
- Gravity
- Gravity is DFRobot’s plug-in connector system for sensors, motors and modules, using standard cables to reduce loose jumper wiring. It matters because Gravity-compatible parts can connect directly to these ports, while non-Gravity parts may need adapters or manual wiring.
