Introduction

  • In this article, I will explain about connecting the liquid Sensor With Arduino Mega 2560.
  • It can generally be used to get the measure of the liquid.
Parts Of Lists
  • Arduino Mega 2560
  • Liquid Sensor.
  • Hook Wires.
Liquid Sensor
  • Liquid level sensors are used for all types of applications.
  • They are extensively used within automobiles.
  • Which rely on a substantial amount of different fluids in order to operate to check.
  • How much gas in the car, windshield washer fluid, oil levels.

Programming
  1. const int sensorPin = 1; //sensor pin connected to analog pin A1
  2. int liquid_level;
  3. void setup()
  4. {
  5. Serial.begin(9600); //sets the baud rate for data transfer in bits/second
  6. pinMode(sensorPin, INPUT); //the liquid level sensor will be an input to the arduino
  7. }
  8. void loop()
  9. {
  10. liquid_level = analogRead(sensorPin); //arduino reads the value from the liquid level sensor
  11. Serial.println(liquid_level); //prints out liquid level sensor reading
  12. delay(1000); //delays 1000ms
  13. }
Explanation
  • In this Article I explained about the Liquid Sensor
  • It can be used to find the quality of the liquid which we have.
  • It can easily print the value in the Serial monitor.
