Product details

FS-IR02 Water Sensor Module, a corrosion-resistant probe is easily mounted and can handle high temperature and high pressure.

This is a photoelectric 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 an high pressure. The sensor is equipped with an interface adapter for compatibility with the DFRobot “Gravity” interface.

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


  1. Compact structure and small size
  2. High precision of liquid level control
  3. High reliability and long life
  4. Easy to use

Package Includes:

1 x Photoelectric Water Level Sensor
