Sound Detection High-Sensitivity Microphone Sensor Module
Acoustic sound detection sensor utilizing an electret condenser microphone and LM393 voltage comparator with adjustable sensitivity potentiometer.
Sound Detection High-Sensitivity Microphone Sensor Module is an original, pre-tested electronic module designed for Arduino, ESP32, Raspberry Pi, robotics, and embedded engineering projects. Includes verified pinout compatibility and nationwide express shipping across Pakistan.
The High-Sensitivity Sound Detection Microphone Module detects acoustic pressure waves in the environment for clap-switch automation and acoustic monitoring.
Key Engineering Features:
- Sensitive Electret Capsule: Detects claps, knocks, engine hum, and loud ambient audio impulses.
- Dual Outputs: Features an Analog Output (A0) for measuring sound wave amplitude and a Digital Output (D0) for trigger alarms.
- Adjustable Threshold: Multi-turn trimpot adjusts sensitivity to eliminate false triggers from low ambient noise.
Common Engineering Applications:
- Clap-activated room light and fan controllers
- Acoustic security alarms (glass-break detection)
- Sound-reactive LED light organs and music visualizers
- Noise-level monitoring in study halls and libraries
What's Included in the Package:
- 1x High-Sensitivity Sound Detection Microphone Sensor Board
Pinout Interfacing & Testing Guide:
Check the silkscreen pin labels (VCC, GND, SDA/SCL or I/O) and confirm whether your microcontroller uses 3.3V or 5V logic.
Wire the power, ground, and signal pins to your Arduino, ESP32, or Raspberry Pi using breadboard jumper wires.
Upload a standard test sketch via Arduino IDE or MicroPython and verify live readings on the Serial Monitor.
