  • Photoelectric Water / Liquid Level / Water Depth Sensor 

    This is a photoelectric water liquid level sensor that is operates using optical principles. The advantages of this photoelectric water liquid level sensor are good sensitivity and no need for mechanical parts. The corrosion resistant probe is easily mounted and can handle high temperature and high pressure. The liquid sensor is equipped with an interface adapter for compatibility with the DFRobot "Gravity" interface.

    Gravity: Analog Photoelectric Water / Liquid Level Sensor For Arduino

    To ease the difficulty of using this Arduino liquid sensor,  a Gravity Interface is adapted to allow plug&play.  The Arduino IO expansion shield is the best match for this sensor 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.
