S signal pin is an analog output pin and will always be connected to the analog inputs pin in arduino.
Ultrasonic water level sensor arduino code.
Open a new sketch file by clicking new.
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.
We made water level meter with arduino platform we used arduino mega2560 but any arduino will work.
Ultrasonic method is similar to radar.
Materials needed for this arduino water level indicator and control using ultrasonic sensor hc.
Open the arduino ide software on your computer.
Arduino water level sensor using ultrasonic sensor etc.
Arduino water level indicator circuit.
Instead of radar wave we are sending ultrasonic wave.
The water sensor has 3 output pins.
The ping sensor measures distance using sonar.
The ultrasonic module is placed 20cm above from the maximum water level.
This procedure is ideal for our needs because ultrasonic sensors are accessible and low priced.
Wrote serial port let s prepare the circuit.
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.
Vcc pin is the power supply pin for the sensor.
Supplies power for the sensor.
Anyone can do it.
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.
Arduino water level sensor.
Arduino water level indicator and control using ultrasonic sensor hc sr04r.
Incoming analog signal read and appointed sensor serial println sensor.
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.
The recommended power of the water level sensor is between 3 3v 5v.
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 circuit will do basically what the aforementioned one will do rather efficiently.
Thus a 20cm is subtracted from the measured distance value.
S this output goes to any analog signal on arduino.
The ultrasonic sensor we re using is the hcsr04 which is quite common and easy to find in electronic stores and also online.
For water below the quarter level only led at pin 8 will be on.
Communication started with 9600 baud void loop int sensor analogread a1.
This project is very basic.
1 arduino uno r3.
Analog output will vary depending on the voltage provided to the sensor.
