Ultrasonic Water Level Sensor Arduino Code

Arduino water level indicator and control using ultrasonic sensor hc sr04r.

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. Open a new sketch file by clicking new. Incoming analog signal read and appointed sensor serial println sensor. Arduino water level sensor.

The ultrasonic sensor is not waterproof though so we will need to keep it protected. S signal pin is an analog output pin and will always be connected to the analog inputs pin in arduino. Arduino water level indicator circuit. Arduino water level sensor using ultrasonic sensor etc.

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. Vcc pin is the power supply pin for the sensor. Communication started with 9600 baud void loop int sensor analogread a1. The ultrasonic module is placed 20cm above from the maximum water level.

The circuit will do basically what the aforementioned one will do rather efficiently. 1 arduino uno r3. We made water level meter with arduino platform we used arduino mega2560 but any arduino will work. S this output goes to any analog signal on arduino.

Analog output will vary depending on the voltage provided to the sensor. Ultrasonic method is similar to radar. Thus a 20cm is subtracted from the measured distance value. This project is very basic.

Materials needed for this arduino water level indicator and control using ultrasonic sensor hc. Coding in the arduino language will control your circuit. In this project two circuits are used. Open the arduino ide software on your computer.

The recommended power of the water level sensor is between 3 3v 5v. The water sensor has 3 output pins. 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. Anyone can do it.

This arduino water level indicator uses an ultrasonic sensor or ping sensor to determine the level of water in the tank. Follow the circuit diagram and make the connections as shown in the image given below. Wrote serial port let s prepare the 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.

The ping sensor measures distance using sonar. 1 ultrasonic sensor hc sr04 procedure. For water below the quarter level only led at pin 8 will be on. Supplies power for the sensor.
