Water Level Indicator Using Arduino

Introduction: Water Level Indicator Using Arduino

About: I am an undergraduate student pursuing B.Tech in EEE(Electrical and Electronics Engineering).I am passionate about creating new stuffs using technology and hungry to learn more and more.

In this project we will be building a water level indicator using arduino & water sensor.

The system would indicate the level of the water (Three different levels) inside a tank with the help of 3 LED and a buzzer to indicate that the tank is full.

This is a beginner level project and has a purposeful implementation as well in your home.

The video is also available in the last step.

So lets get started....

Step 1: Components Required

You will need the following materials for making your own Water Level Indicator

>Arduino Uno

>Breadboard

>3 LED (red,green,yellow)

>Buzzer (x1)

>Jumper wires

>Water level sensor

> 220 ohms resistor (x3)

Step 2: Assemble LED on Breadboard

-Use LED of 3 different colors

RED( indicating extremely low level)

YELLOW (indicating half water level)

GREEN(indicating full water level)

-connect the cathode of each led to power rail(blue rail) on breadboard which would be the ground supply.

-connect the anode of LED's to different nodes.

-connect 220 ohms resistor in series with each LED.

Step 3: Make Connections With Arduino and LED

Make connections for LED with digital pins on arduino as follows:

RED => Digital pin 13

YELLOW => Digital pin 12

GREEN => Digital pin 11

Step 4: Connect the Water Sensor With Arduino

Connect the water level sensor to arduino as follows:

Water Sensor pins => Arduino pins

- => GND

+ => VCC

S => A0

Step 5: Connect Buzzer

Connect the buzzer to Digital pin 8 of Arduino.

Step 6: Upload Sketch

Upload the sketch to your Arduino uno using the Arduino IDE.

Step 7: Done!! Watch Tutorial

As water level changes, corresponding LED will light up. Checkout the video once. I hope that you found this instructable on Water Level Indicator useful.

Does it work on 8051 board

it says to upgrade to premium

where is the code exactly ?

I HAVE DONE IT EXACTLY BUT IT DID'NT WORK
