Description

This sound sensor module utilizes a high-sensitivity electric condenser microphone to convert acoustic pressure waves into an electrical signal. The onboard circuitry amplifies this signal and provides a raw analog output proportional to the sound intensity, suitable for precise sound level analysis.

The module also incorporates a comparator circuit that outputs a digital high/low signal when the audio amplitude exceeds a user-adjustable threshold, enabling simple sound-activated switching. Its 5V DC power requirement and compact form factor make it ideal for embedded audio applications in interactive devices and environmental monitoring systems.

Key Features

  • 5V DC Power Supply with low current consumption.
  • High-Sensitivity Electric Condenser Microphone element.
  • Dual Output: Analog output for sound level and digital comparator output for threshold detection.
  • Onboard potentiometer for adjusting the sound detection sensitivity threshold.
  • Power and digital output indicator LEDs for operational status.
  • Compact PCB design with a 3mm mounting hole for easy fixture.
  • Optimized performance-to-cost ratio for educational and prototyping use.

Applications

  • Interactive voice-activated switches and clap-controlled devices.
  • Sound level meters and noise monitoring systems for environmental studies.
  • Audio detection for security systems and intrusion alarms.
  • Sound-reactive lighting and visual effects controllers.
  • Educational projects for demonstrating analog signal acquisition and threshold detection with Arduino or Raspberry Pi.

Frequently Asked Questions

What is the operating voltage range for this sound sensor module?

The module is designed for a 5V DC power supply. It is crucial to stay within this rating, as exceeding it may damage the onboard microphone and comparator circuitry. It can be powered directly from the 5V pin of an Arduino or similar microcontroller board.

How do I use the analog and digital outputs?

The analog output pin provides a voltage signal that varies with the detected sound intensity, which can be read by an MCU's ADC pin for sound level measurement. The digital output pin toggles high or low when the sound amplitude crosses the threshold set by the onboard potentiometer, ideal for triggering events without continuous ADC sampling.

Can I adjust the sound detection sensitivity?

Yes, sensitivity is adjustable via the blue potentiometer on the module. Turning it clockwise typically increases the threshold, requiring a louder sound to trigger the digital output. Fine-tuning allows adaptation to different ambient noise environments.
