Sensitivity Sound Detection Sensor Module Voice Sensor

Description

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, analog 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 10mm
