Ultrasonic Water Level Sensor Arduino Code

1 ultrasonic sensor hc sr04 procedure.

Ultrasonic water level sensor arduino code.

And the leds on pin 9 10 11 gets on as the water level crosses the quarter half and three quarter heights respectively. This project is very basic. 1 arduino uno r3. S this output goes to any analog signal on arduino.

Materials needed for this arduino water level indicator and control using ultrasonic sensor hc. Open a new sketch file by clicking new. Thus a 20cm is subtracted from the measured distance value. The ultrasonic module is placed 20cm above from the maximum water level.

We made water level meter with arduino platform we used arduino mega2560 but any arduino will work. The ultrasonic sensor is not waterproof though so we will need to keep it protected. This procedure is ideal for our needs because ultrasonic sensors are accessible and low priced. Wrote serial port let s prepare the circuit.

The water sensor has 3 output pins. Anyone can do it. Coding in the arduino language will control your circuit. The ping sensor measures distance using sonar.

Arduino water level indicator circuit. The circuit will do basically what the aforementioned one will do rather efficiently. 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. Vcc pin is the power supply pin for the sensor.

Open the arduino ide software on your computer. Arduino water level sensor using ultrasonic sensor etc. Arduino water level indicator and control using ultrasonic sensor hc sr04r. For water below the quarter level only led at pin 8 will be on.

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. Analog output will vary depending on the voltage provided to the sensor. S signal pin is an analog output pin and will always be connected to the analog inputs pin in arduino. Supplies power for the sensor.

The ultrasonic sensor we re using is the hcsr04 which is quite common and easy to find in electronic stores and also online. This arduino water level indicator uses an ultrasonic sensor or ping sensor to determine the level of water in the tank. In this project two circuits are used. The recommended power of the water level sensor is between 3 3v 5v.

Follow the circuit diagram and make the connections as shown in the image given below. Ultrasonic method is similar to radar. Arduino water level sensor. Communication started with 9600 baud void loop int sensor analogread a1.
