Features:
The High Sensitivity Sound Detection Sensor (4 Pins) features a CMA-6542PF electret microphone and provides both analog and digital outputs. It uses an LM393 comparator for threshold detection and includes an onboard 3296W potentiometer for sensitivity adjustment. Analog output reflects real-time sound intensity, while the digital output goes HIGH when the set threshold is exceeded. Compatible with Arduino, ESP32, and Raspberry Pi.

Specifications:
  • Operating voltage: 3.3V to 5.5V DC
  • Output type: Digital (D0) and Analog (A0)
  • Microphone type: CMA-6542PF electret condenser
  • Microphone sensitivity: -42dB +-3dB
  • Comparator IC: LM393
  • Sensitivity adjustment: 3296W potentiometer
  • Output behavior: D0 goes HIGH when sound exceeds threshold
  • Current consumption: ~0.5mA
