🔊 Sound Detection Sensor Module 🔊
This sound detection sensor module uses an electret microphone to detect sound in the surrounding environment. When the sound level exceeds a certain threshold, it outputs a digital signal (HIGH/LOW), which can be used to trigger alarms, lights, or control robots. Sensitivity can be easily adjusted using the onboard potentiometer.
✅ Technical Specifications:
- Sensor Type: Electret Microphone.
- Operating Voltage: 3.3V – 5V DC.
- Pins: 3 (VCC, GND, OUT).
