It is a DFRobot Non-contact Capacitive Liquid Level Sensor for Tube OD≤10mm. This is a non-contact liquid level sensor with a status indicator and adjustable sensitivity. It is especially suitable for detecting the liquid level of all sorts of non-metal tubes(outer diameter D≤10MM). The status feedback of the sensor can be given in real-time. Besides that, the sensor comes with a 4pin sensor adaptor that can directly collect digital signal, convenient for connecting with Arduino or other main-controllers. This liquid level sensor can be widely used in liquid detection of water dispenser, small pipes, and perfusion tubes.

This DFRobot Non-contact Capacitive Liquid Level Sensor is developed on advanced signal process technology by high-speed signal processing chip. It can measure the liquid level of a closed container and it will not be affected by corrosive liquids like strong acid and alkali, or other impurities.
