Tutorial: How to use US-015 Ultrasonic Sensor Module

The US-015 sensor measures distances with precision and is suitable for projects that require detailed distance measurement, such as home automation or obstacle avoidance systems.

What you need

• Arduino Uno or compatible
• 5V power supply cable
• 10kΩ resistor
• Breadboard and 0.1″ pins

Steps

1. 1. Connect the module to the breadboard.
2. 2. Connect the VCC pin to the 5V of Arduino.
3. 3. Connect the GND pin to the GND of Arduino.
4. 4. Connect the TRIG pin to a digital pin (e.g., D10).
5. 5. Connect the ECHO pin to a digital pin (e.g., D11).
6. 6. Connect the 10kΩ resistor between VCC and GND.
7. 7. Upload the code to Arduino.
8. 8. Test the module with Arduino IDE.

Example code

```
void setup() {
  pinMode(10, OUTPUT);
  pinMode(11, INPUT);
}

void loop() {
  digitalWrite(10, LOW);
  delayMicroseconds(10);
  digitalWrite(10, HIGH);
  delayMicroseconds(10);
  digitalWrite(10, LOW);

  long duration = pulseIn(11, HIGH);
  int distance = duration * 0.034 / 2;
  Serial.print("Distanza: ");
  Serial.println(distance);
}
```

Mini project

Create an obstacle avoidance system for a mobility robot.

Common mistakes

• Connect ECHO to an analog pin.
• Omit the 10kΩ resistor.
• Power the module with a different power supply than 5V.
• Use a digital pin for TRIG and ECHO without distinguishing between the two.

Recommended accessories

• Arduino Uno
• Breadboard
• 0.1″ pins
• 10kΩ resistor
