Connect Liquid Sensor With Arduino Mega 2560

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.

Liduid 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 levles.

Connection

 

Sensor	Board
Vcc	5V
Gnd	Gnd
Vin	A1

Programming

const int sensorPin = 1; //sensor pin connected to analog pin A1
int liquid_level;
void setup()
{
    Serial.begin(9600); //sets the baud rate for data transfer in bits/second
    pinMode(sensorPin, INPUT); //the liquid level sensor will be an input to the arduino
}
void loop()
{
    liquid_level = analogRead(sensorPin); //arduino reads the value from the liquid level sensor
    Serial.println(liquid_level); //prints out liquid level sensor reading
    delay(1000); //delays 1000ms
}

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.
