Название: Working of the Sound Sensor Module

The sound sensor module functions by capturing sound waves from the environment and converting them into electrical signals.

Here’s a brief overview of how it works:

Sound Capture:The microphone in the sound sensor captures sound waves, which are variations in air pressure caused by sound events;
Signal Amplification: The captured sound signal is weak, so it passes through an amplifier to boost its amplitude while maintaining its fidelity;
Threshold Comparison: The amplified signal is compared to a predefined threshold level using a comparator. When the sound level crosses this threshold, the module generates an output signal;
Output Signal:The output signal is available at the OUT pin of the sound sensor module. It can be either digital (high or low) or analog (a varying voltage level), depending on the module’s configuration;

By interfacing the sound sensor with Arduino, you can capture and process these signals, enabling you to respond to sound events in your projects.
