Ultrasonic Water Level Sensor Arduino Code

The water sensor has 3 output pins.

Ultrasonic water level sensor arduino code.

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. The ping sensor measures distance using sonar. We made water level meter with arduino platform we used arduino mega2560 but any arduino will work. Open the arduino ide software on your computer.

And the leds on pin 9 10 11 gets on as the water level crosses the quarter half and three quarter heights respectively. Communication started with 9600 baud void loop int sensor analogread a1. Arduino water level indicator and control using ultrasonic sensor hc sr04r. Incoming analog signal read and appointed sensor serial println sensor.

The circuit will do basically what the aforementioned one will do rather efficiently. Follow the circuit diagram and make the connections as shown in the image given below. 1 arduino uno r3. This procedure is ideal for our needs because ultrasonic sensors are accessible and low priced.

The ultrasonic sensor is not waterproof though so we will need to keep it protected. Instead of radar wave we are sending ultrasonic wave. 1 ultrasonic sensor hc sr04 procedure. Open a new sketch file by clicking new.

Analog output will vary depending on the voltage provided to the sensor. The ultrasonic module is placed 20cm above from the maximum water level. 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. The ultrasonic sensor we re using is the hcsr04 which is quite common and easy to find in electronic stores and also online.

Coding in the arduino language will control your circuit. Anyone can do it. Supplies power for the sensor. Materials needed for this arduino water level indicator and control using ultrasonic sensor hc.

For water below the quarter level only led at pin 8 will be on. Thus a 20cm is subtracted from the measured distance value. 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. Wrote serial port let s prepare the circuit.

Ultrasonic method is similar to radar. Vcc pin is the power supply pin for the sensor. This arduino water level indicator uses an ultrasonic sensor or ping sensor to determine the level of water in the tank. Arduino water level sensor using ultrasonic sensor etc.

Arduino water level indicator circuit. Arduino water level sensor. S this output goes to any analog signal on arduino. The recommended power of the water level sensor is between 3 3v 5v.
