Immersible Ultrasonic Transceiver Diameter 16MM Dual Function (Transmitter + Receiver)

Description

Tutorial: How to Use the Waterproof Ultrasonic Transceiver Diameter 16MM

This waterproof ultrasonic transceiver is ideal for distance measurement projects and zero-contact sensors, suitable for both beginners and experts.

What you need

• Arduino Uno or compatible
• jumper wire
• USB power supply

Steps

1. Connect the ultrasonic transceiver to the chosen Arduino pin using a jumper wire.
2. Check the module’s power supply (5V or 3.3V) and ensure it matches the Arduino’s output.
3. Install the NewPing library to facilitate control of the ultrasonic transceiver.
4. Write an Arduino sketch that initializes the ultrasonic transceiver and reads distance values.
5. Check the datasheet for specific module commands to obtain accurate data.
6. Try modifying the sketch by adding an LCD display to show the measurements.
7. Test the device in different environments to verify the accuracy of the detections.
8. Adapt the sketch to your specific project, exploring further features of the module.

Example code

const int trigPin = 9;
const int echoPin = 10;
NewPing sonar(trigPin, echoPin, MAX_DISTANCE);

void setup() {
  Serial.begin(9600);
}

void loop() {
  unsigned int uS = sonar.ping();
  float cm = uS / US_ROUNDTRIP_CM;
  Serial.print(cm);
  Serial.println("cm");
}

Mini project

Create a home security system that detects the presence of objects or people in a specific area.

Common mistakes

• Do not verify the correct power supply of the module.
• Omit installing the necessary libraries to control the device.
• Ignore the delay times between one call and another of the ping() function.
• Use only the basic function without exploring further specific commands of the module.

Recommended accessories

• LCD Display to display measurements in real-time.
• Batteries or external power supply to test the device away from a computer.
• USB cable to connect the Arduino to power or to the computer.
• Electronic prototyping kit to build the circuit.
