Ultrasonic Water Level Sensor Arduino Code

Anyone can do it.

Ultrasonic water level sensor arduino code.

Incoming analog signal read and appointed sensor serial println sensor. S signal pin is an analog output pin and will always be connected to the analog inputs pin in arduino. 1 arduino uno r3. Follow the circuit diagram and make the connections as shown in the image given below.

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. Open the arduino ide software on your computer. S this output goes to any analog signal on arduino. The water sensor has 3 output pins.

Arduino water level sensor using ultrasonic sensor etc. Arduino water level indicator circuit. The circuit will do basically what the aforementioned one will do rather efficiently. 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.

Ultrasonic method is similar to radar. This procedure is ideal for our needs because ultrasonic sensors are accessible and low priced. Thus a 20cm is subtracted from the measured distance value. Arduino water level sensor.

For water below the quarter level only led at pin 8 will be on. Arduino water level indicator and control using ultrasonic sensor hc sr04r. 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. Materials needed for this arduino water level indicator and control using ultrasonic sensor hc.

The ultrasonic sensor we re using is the hcsr04 which is quite common and easy to find in electronic stores and also online. Wrote serial port let s prepare the circuit. Instead of radar wave we are sending ultrasonic wave. Analog output will vary depending on the voltage provided to the sensor.

The ultrasonic module is placed 20cm above from the maximum water level. Open a new sketch file by clicking new. This arduino water level indicator uses an ultrasonic sensor or ping sensor to determine the level of water in the tank. Coding in the arduino language will control your circuit.

Supplies power for the sensor. And the leds on pin 9 10 11 gets on as the water level crosses the quarter half and three quarter heights respectively. 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.

The ping sensor measures distance using sonar. 1 ultrasonic sensor hc sr04 procedure. This project is very basic. Vcc pin is the power supply pin for the sensor.
