Product Description

Ultrasonic Distance Sensor HC-SR04 - SONAR

Measure Distance with Precision and Ease

The Ultrasonic Distance Sensor HC-SR04, available at Robogearbd.com, is a reliable and easy-to-use sensor for measuring distances with high accuracy. Utilizing ultrasonic waves, this sensor can detect the distance to an object and provide precise measurements. Ideal for robotics, obstacle detection, and distance measurement applications, the HC-SR04 offers a cost-effective solution for various projects.

Why Choose HC-SR04?

  • Accurate Distance Measurement: Measures distances from 2 cm to 4 meters with an accuracy of up to 3 mm.
  • Simple Interface: Easy to integrate with microcontrollers like Arduino using just four pins: VCC, GND, TRIG, and ECHO.
  • Non-Contact Measurement: Uses ultrasonic waves to detect objects, making it suitable for non-contact applications.
  • Cost-Effective: Provides high precision and reliability at an affordable price.
  • Versatile Applications: Perfect for use in robotics, automation, and distance sensing projects.

How to Get Started?

  1. Power the Sensor: Connect the VCC pin to a 5V power source and the GND pin to ground.

  2. Connect to a Microcontroller: Connect the TRIG pin to a digital output pin on your microcontroller and the ECHO pin to a digital input pin.

  3. Send a Trigger Pulse: Send a 10 µs pulse to the TRIG pin to start the measurement. The sensor will emit an ultrasonic pulse.

  4. Receive the Echo Pulse: Measure the duration of the pulse received on the ECHO pin. This duration correlates to the distance of the object.

  5. Calculate Distance: Use the formula Distance = (Duration x Speed of Sound) / 2 to calculate the distance. The speed of sound is approximately 343 meters per second.

  6. Test and Adjust: Verify the distance measurements and adjust your setup or code as necessary to ensure accurate readings.
