Specification:

This module uses a professional microphone amplifier IC with low output noise, small size, high sensitivity, fixed gain of 20dB, and supports 3.3v and 5v power supply modes.

The Sound detection module has two outputs:

1. AO, analogue output, real-time output voltage signal of the microphone

2. DO, when the sound intensity reaches a certain threshold, the output high and low signal

Voltage : 3.3V to 5V

Differential Comparator : LM393

Microphone : Electret condenser

Size : 45mm x 17mm x 10m         

Package Contains:

1Nos High Sensitivity Sound Detection Sensor Module
