This is a photoelectric water liquid level sensor that is operates using optical principles. 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 DFRobot "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 sensor 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.

can this sensor detect the pH level or temperature of water? if no, what are the sensors you have to detect the pH level or temperature of water which is compatible with rasperiPi? ( Pagupathi A/P Devandran Pillai , 29/02/2020 )

Hi, we're sorry as it cannot detect the pH level or temperature of water. You may refer to this link for a more suitable product. However, you'll need a converter in order to be compatible with with Raspberry Pi. Thanks :)

can this sensor connected using 2units concurrently?to measure different level ( faisal, 10/05/2019 )
Hi, yes you can as the output in term of the signal.
is it submersible and have an example on how to use it? ( Paan, 08/04/2019 )
Hi, yes it is submersible. You may refer to this link on how to use it.
