This is a Gravity: Photoelectric High Accuracy Liquid Level Sensor. It is operates using traditional optical principles. The advantages of this are a high sensitivity and no need for mechanical parts meaning less calibration! The corrosion resistant probe is easily mounted and can handle high temperatures and high pressures. The sensor is equipped with an interface adapter for compatibility with the DFRobot Gravity interface.

The Gravity: Photoelectric High Accuracy Liquid Level Sensor is equipped with an interface adapter for compatibility with the DFRobot Gravity interface. To ease the difficulty of using this arduino liquid sensor, aGravity Interface is adapted to allow plug&play. The Arduino IO expansion shield is the best match for this senor connecting to Arduino. As this liquid sensor is able to work at 3.3V which makes it compatible with Raspberry Pi,intel edison, joule and curie.

Note:Avoid placing the sensor near bright lights or in direct sunlight as these can cause interference.
