Gravity Flexible Non-Contact Capacitive Liquid Level Sensor

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.
