Pin Configuration

  • Mounting Bracket for HC-SR04 Ultrasonic Module Documentation
  • Overview
  • The Mounting Bracket for HC-SR04 Ultrasonic Module is a convenient and compact solution for integrating the popular HC-SR04 ultrasonic sensor module into various IoT projects. This bracket provides a secure and stable platform for the sensor module, ensuring accurate distance measurements and easy installation.
  • Pin Description
  • The HC-SR04 Ultrasonic Module has four pins, which are clearly labeled on the bracket. Here's a detailed description of each pin:
  • 1. VCC (Power Input)
  • Pin function: Power supply input
  • Pin type: Power pin
  • Recommended voltage: 5V DC (do not exceed 6V)
  • Description: Connect the VCC pin to a 5V power source, such as a microcontroller or a breadboard power rail.
  • 2. Trig (Trigger Input)
  • Pin function: Trigger signal input
  • Pin type: Digital input
  • Description: The Trig pin is used to initiate the ultrasonic ranging process. When a high signal (5V) is applied to this pin, the module sends out an ultrasonic burst and starts measuring the distance.
  • 3. Echo (Echo Output)
  • Pin function: Echo signal output
  • Pin type: Digital output
  • Description: The Echo pin outputs a digital signal that represents the time it took for the ultrasonic burst to bounce back from an object. The duration of the echo signal is proportional to the distance.
  • 4. GND (Ground)
  • Pin function: Ground connection
  • Pin type: Ground pin
  • Description: Connect the GND pin to a common ground point, such as a microcontroller's GND pin or a breadboard's ground rail.
  • Connection Structure
  • To connect the HC-SR04 Ultrasonic Module to a microcontroller or a development board, follow this structure:
  • VCC (Power Input) 5V Power Source (e.g., microcontroller's VCC pin or breadboard power rail)
  • Trig (Trigger Input) Digital Output Pin of the microcontroller (e.g., Arduino's digital pin)
  • Echo (Echo Output) Digital Input Pin of the microcontroller (e.g., Arduino's digital pin)
  • GND (Ground) Common Ground Point (e.g., microcontroller's GND pin or breadboard ground rail)
  • Important Notes
  • Make sure to use a level converter if the microcontroller's voltage is not 5V.
  • Avoid connecting the Trig pin directly to a digital output pin that can source current, as this may damage the sensor module. Instead, use a transistor or a buffer to drive the Trig pin.
  • Ensure that the power supply is stable and can provide enough current to the sensor module.
  • Follow proper wiring and soldering practices to avoid electrical noise and damage to the sensor module.
  • By following these guidelines, you can successfully integrate the HC-SR04 Ultrasonic Module into your IoT project and start measuring distances with accuracy.
