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....
Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Components Required
You will need the following materials for making your own Water Level Indicator
>3 LED (red,green,yellow)
>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.
