A Sound Microphone Detection Sensor Module detects environmental sound intensity using an electret microphone and an LM393 comparator.
🛠️ Key Details
  • Voltage: Works at 3.3V to 5V DC.
  • Adjustment: Built-in potentiometer changes sound sensitivity thresholds.
  • LEDs: Indicators show power status and sound trigger alerts. 
📌 Pinout
  • VCC: Power input (3.3V - 5V).
  • GND: Ground connection.
  • DO (Digital Output): Sends a high/low signal when sound crosses the set threshold.
  • AO (Analog Output): Sends a continuous voltage signal matching the real-time sound wave. 
💡 Common Uses
  • Clap switches to toggle lights.
  • Security alarms to detect loud knocks or breaks.
  • Voice-activated robotics.
Note: This sensor is ideal for detecting sound presence and volume, not for recording high-quality audio or recognizing specific words.
