We connect the sensor to an arduino and as per the changing water level new signal readings would be sent letting us know the level.
Ultrasonic water level sensor arduino code.
The water sensor has 3 output pins.

Arduino water level sensor.
Arduino water level sensor using ultrasonic sensor etc.
The recommended power of the water level sensor is between 3 3v 5v.
The ultrasonic sensor we re using is the hcsr04 which is quite common and easy to find in electronic stores and also online.
An ultrasonic well above human hearing pulse is transmitted from the unit and distance to target is determined by measuring the time required for the echo return.
Instead of radar wave we are sending ultrasonic wave.
Wrote serial port let s prepare the circuit.
Ultrasonic method is similar to radar.
This project is very basic.
Incoming analog signal read and appointed sensor serial println sensor.
In this project two circuits are used.
We made water level meter with arduino platform we used arduino mega2560 but any arduino will work.
Analog output will vary depending on the voltage provided to the sensor.
The ultrasonic sensor is not waterproof though so we will need to keep it protected.
Communication started with 9600 baud void loop int sensor analogread a1.
Supplies power for the sensor.
For water below the quarter level only led at pin 8 will be on.
And the leds on pin 9 10 11 gets on as the water level crosses the quarter half and three quarter heights respectively.
Coding in the arduino language will control your circuit.
Transmitter circuit transmitter circuit is shown in the figure below fig1 in this circuit an ultrasonic sensor is connected to pin d9 and d10 pin of arduino.
Arduino water level indicator circuit.
Thus a 20cm is subtracted from the measured distance value.
S signal pin is an analog output pin and will always be connected to the analog inputs pin in arduino.
S this output goes to any analog signal on arduino.
Anyone can do it.
Follow the circuit diagram and make the connections as shown in the image given below.
This procedure is ideal for our needs because ultrasonic sensors are accessible and low priced.
The ultrasonic module is placed 20cm above from the maximum water level.
Materials needed for this arduino water level indicator and control using ultrasonic sensor hc.
Arduino water level indicator and control using ultrasonic sensor hc sr04r.
Open the arduino ide software on your computer.
This arduino water level indicator uses an ultrasonic sensor or ping sensor to determine the level of water in the tank.
The circuit will do basically what the aforementioned one will do rather efficiently.
