Analog Sound Sensor to detect sound and act upon it using Arduino.

  • It can detect the sound intensity of the surrounding environment.
  • Note: This sensor can only identify the presence or absence of sound (according to the principle of vibration) and cannot identify the size of the sound or the sound of a specific frequency.
  • Sensitivity is adjustable (the blue digital potentiometer is used to adjust the sensitivity).
  • Working voltage 3.3V-5V
  • Output form Digital switch output (0 and 1 high and low level)
  • With fixing bolt holes for easy installation
  • Small board PCB size: 3.2cm * 1.7cm

Module wiring instructions:

  • VCC externally connects 3.3V-5V voltage (can be directly connected with 5v microcontroller and 3.3v microcontroller)
  • GND connects to GND
  • OUT small board switch output interface (0 and 1)

Instructions for use:

  • The sound module is most sensitive to the intensity of ambient sound, and is generally used to detect the sound intensity of the surrounding environment.
  • When the module’s environmental sound intensity does not reach the set threshold, OUT outputs a high level; when the external environmental sound intensity exceeds the set threshold, the module OUT outputs a low level.
  • The digital output OUT of the small board can be directly connected with the single-chip microcomputer, and the high and low level can be detected by the single-chip microcomputer, thereby detecting the sound of the environment.
  • The small board digital output OUT can directly drive the relay module of our shop, which can form a voice-activated switch.
