Photoelectric Water

Introduction

This is a photoelectric liquid level sensor that is operates using traditional optical principles. The advantages of this are a high sensitivity and no need for mechanical parts - meaning less calibration! The corrosion resistant probe is easily mounted and can handle high temperatures and high pressures. 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.

int Liquid_level=0;
void setup() {
 Serial.begin(9600);
 pinMode(5,INPUT);
}

void loop() {
Liquid_level=digitalRead(5);
Serial.print("Liquid_level= ");Serial.println(Liquid_level,DEC);
delay(500);
}

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.
