Grove - Water Level Sensor (10CM) for Arduino

The Grove Water Level Sensor is a very accurate sensor that can be helpful in water level sensing applications. It is completely waterproof and uses capacitive pads to detect water levels up to 10cm. Features High measurement accuracy: Since the sensor is based on capacitive sensing, The measurement accuracy is up to ±5 mm. Outstanding corrosion resistance: Inevitably, some liquids may be corrosive during use, and with the help of corrosion-resistant materials, the sensor can be used for a long time. Grove unified socket: The sensor ensures "Plug and Play" and could be versatile for various applications. Description The Grove Water Level Sensor is a very accurate sensor that can be helpful in water level sensing applications. It is completely waterproof and uses capacitive pads to detect water levels up to 10cm. We used capacitive pads on the PCB of the module and did conformal coating over the PCB to make the sensor protect against moisture, dust, chemicals and high temperatures. We believe that this technique will allow you to make accurate water level measurements (±5mm accuracy) easily Let’s look at the difference between few water level sensing methods. Ultrasonic Distance Sensor Sensor based on Resistance Grove - Water Level Sensor Principle Ultrasonic Waves Resistance Capacitance Communication Interface Digital Analog I2C Operating Voltage 3.3/5V 3.3/5V 3.3/5V Waterproof No Yes Yes Note The blue oil layer on the surface of the module’s capacitance sensing area should be kept intact. When the oil layer is damaged and the test object is a conductive liquid, the test data may be abnormal. Attention When testing, the highest liquid level inserted should not exceed the white dividing line, otherwise it will cause a short circuit.
