Gravity Capacitive Level Sensor contactless flexible

The DFRobot Gravity level sensor detects liquid without contact through the wall of a non-conductive container. The sensor is flat and flexible and is stuck to the outside of the container with the temperature-resistant, waterproof 3M adhesive tape on its back, also on curved surfaces. The wall may be at most 5 mm thick. When the liquid rises to the height of the sensor, the measured capacitance changes and the digital output switches to low.

Note: Suitable for containers made of plastic, glass or ceramic, not for metal or other conductive containers.

Note: The connection cable can be converted to male pins with a Dupont cable M-M, so that it also fits an Arduino UNO.
