The Sound Detection Sensor Module is a 4-pin electret-microphone sensor built around the LM393 comparator, designed to detect ambient sound and trigger a digital output once a set volume threshold is crossed. It suits clap switches, noise-activated alarms and sound-reactive lighting projects.

Key features:

  • Electret Microphone: Picks up ambient sound and converts it into an analog voltage proportional to volume.
  • Dual Signal Output: Provides an analog output (AO) for sound level and a digital output (DO) that switches once the threshold is exceeded.
  • LM393 Comparator: Delivers a fast, stable digital trigger signal free of noise.
  • Adjustable Sensitivity: An onboard potentiometer sets the detection threshold to match the environment.
  • Compact 4-Pin Header: VCC, GND, DO and AO pins connect directly to Arduino, ESP8266 or other microcontroller boards.
  • Status LED: An onboard indicator lights up whenever the digital output is triggered.
