Ultrasonic Water Level Sensor Arduino Code

Arduino water level indicator circuit.

Ultrasonic water level sensor arduino code.

The water sensor has 3 output pins. Open the arduino ide software on your computer. Wrote serial port let s prepare the circuit. Communication started with 9600 baud void loop int sensor analogread a1.

This arduino water level indicator uses an ultrasonic sensor or ping sensor to determine the level of water in the tank. 1 ultrasonic sensor hc sr04 procedure. S signal pin is an analog output pin and will always be connected to the analog inputs pin in arduino. This procedure is ideal for our needs because ultrasonic sensors are accessible and low priced.

In this project two circuits are used. Analog output will vary depending on the voltage provided to the sensor. Thus a 20cm is subtracted from the measured distance value. For water below the quarter level only led at pin 8 will be on.

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

This project is very basic. The ultrasonic module is placed 20cm above from the maximum water level. Anyone can do it. 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.

Arduino water level sensor using ultrasonic sensor etc. Incoming analog signal read and appointed sensor serial println sensor. Open a new sketch file by clicking new. And the leds on pin 9 10 11 gets on as the water level crosses the quarter half and three quarter heights respectively.

Arduino water level sensor. Coding in the arduino language will control your circuit. Vcc pin is the power supply pin 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.

We made water level meter with arduino platform we used arduino mega2560 but any arduino will work. The circuit will do basically what the aforementioned one will do rather efficiently. Supplies power for the sensor. Ultrasonic method is similar to radar.

1 arduino uno r3. Instead of radar wave we are sending ultrasonic wave. Follow the circuit diagram and make the connections as shown in the image given below. Arduino water level indicator and control using ultrasonic sensor hc sr04r.
