The advantages of this are good sensitivity and no need for mechanical parts - meaning less calibration! The corrosion resistant probe is easily mounted and can handle high temperature and high pressure. The sensor is equipped with an interface adapter for compatibility with the "Gravity" interface. To ease the difficulty of using this sensor, a Gravity Interface is adapted to allow plug&play. The Arduino IO expansion shield is the best match for this senor connecting to Arduino. As this 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.
