Ultrasonic Water Level Sensor Arduino Code

Arduino water level sensor.

Ultrasonic water level sensor arduino code.

This project is very basic. Ultrasonic method is similar to radar. Materials needed for this arduino water level indicator and control using ultrasonic sensor hc. We made water level meter with arduino platform we used arduino mega2560 but any arduino will work.

Instead of radar wave we are sending ultrasonic wave. 1 ultrasonic sensor hc sr04 procedure. Arduino water level sensor using ultrasonic sensor etc. For water below the quarter level only led at pin 8 will be on.

The circuit will do basically what the aforementioned one will do rather efficiently. The water sensor has 3 output pins. The recommended power of the water level sensor is between 3 3v 5v. The ultrasonic sensor we re using is the hcsr04 which is quite common and easy to find in electronic stores and also online.

Anyone can do it. Analog output will vary depending on the voltage provided to the sensor. 1 arduino uno r3. 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.

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. The ultrasonic sensor is not waterproof though so we will need to keep it protected. In this project two circuits are used. This procedure is ideal for our needs because ultrasonic sensors are accessible and low priced.

Open a new sketch file by clicking new. Incoming analog signal read and appointed sensor serial println 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 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. This arduino water level indicator uses an ultrasonic sensor or ping sensor to determine the level of water in the tank. Communication started with 9600 baud void loop int sensor analogread a1. Follow the circuit diagram and make the connections as shown in the image given below.

Open the arduino ide software on your computer. Thus a 20cm is subtracted from the measured distance value. The ping sensor measures distance using sonar. Wrote serial port let s prepare the circuit.

S signal pin is an analog output pin and will always be connected to the analog inputs pin in arduino. Coding in the arduino language will control your circuit. Arduino water level indicator circuit. Vcc pin is the power supply pin for the sensor.
