Product description: Non-contact liquid level sensor - digital - DFRobot SEN0368

Manufactured by the companyDFRobotThe non-contact capacitive liquid level sensor is equipped with astatus indicator and the possibility of adjusting sensitivity. This product can be used to detect liquids in non-metallic containers or pipes(external diameter greater than 11 mm). Feedback on the status of the sensor takes place in real time. In addition, this sensor is equipped with a 4-pin adapter, which allows the direct collection of a digital signal, convenient for connection toArduinoor other microcontrollers. This product features a wide applicability in detecting liquid in a tank, water dispenser, etc. This non-contact liquid level sensor is developed with advanced signal processing technology using high-speed chip. The measurement is not affected by the thickness of the container walls, contamination and the presence of acids and alkalis.

Matthias 31.05.2023 Confirmed purchase Translated review
Super product, switching point optimally adjustable. In my case, switches a small water pump for watering the geraniums with the help of a coupling relay.
Krzysztof 19.05.2023 Confirmed purchase Translated review
Good documentation, 3.3V converter included (5..12V power supply). Good adjustable sensitivity, well-designed elastic capacitive electrodes - easy to adjust to the shape of the tank.
Andreas 30.03.2023 Confirmed purchase Translated review
If everything worked fine, I integrated the sensors with an Attiny84 as OneWire sensors. What is not so good is the documentation of DFRobot. The jumpers for pull and down are not well explained there
