Introduction

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 and

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.

ExpectedResults

When liquid comes in to contact with the sensor probe the microcontroller will output HIGH

logic. When the liquid is not in contact with the probe the microcontroller will output LOW

logic.
