Methods of Detecting Water Level Arduino Using Ultrasonic Sensor and Funduino Water Sensor

About: For more project and tutorial visit my YouTube Channel Smart Technology

In this project,I'll show you how create an inexpensive water detector using two methods :

1. Ultrasonic sensor (HC-SR04).

2. Funduino water sensor.


Step 1: Using Ultrasonic Sensor As Detector

The idea of ultrasonic sensor came from the bats and dolphins, they estimate distance by using the echolocation process—sound waves transmitted, bounced back and received, with the time difference used to calculate the distance of objects.

First of all we need to trigger the ultrasonic sensor module to transmit signal by using arduino and then wait for receive ECHO. Arduino reads the time between triggering and Received ECHO. We know that speed of sound is around 340m/s. so we can calculate distance by using given formula:
Distance= (travel time/2) * speed of sound Where speed of sound around 340 meter per second.

What You Will Need ?

For this project you will need:

-Arduino uno

-Breadboard Water

-Ultrasonic Sensor

-Led (optional)

The Circuit :

So on this sensor you have 4 pins. Vcc - this pin is connected to 5V+. Trig - you need to define this pin in your program. Echo -this pin is the same as Trig you also need to define him. GND - this pin is connected to ground.

Step 3: Using Water Sensor As Detector

There are a lot of uses for this sensor module. It can be used to detect the presence or absence of water, accurately gauge the water surface level, or you can even accurately gauge the volume of water present by using a volume measurement device such as a measuring cup in conjunction with the analog water sensor module.

What You Will Need ?

For this project you will need:

-Arduino uno

-Breadboard Water

-Water Sensor

-Led (optional)

The Circuit :
The connections are so easy!

Vcc - Arduino 5V

GND - Arduino GND

A0 - Arduino Analog pin 0

Anode Led - Arduino Pin13

Cathode Led - Arduino GND
