1. Introduction
The function of the sound sensor module is equivalent to a microphone (microphone).It is used to receive sound waves, display the vibration image of sound, but cannot measure the intensity of noise.The sensor is built-in with a sound-sensitive capacitive condenser microphone.Sound waves cause the piezoelectric film inside the microphone to vibrate, resulting in a change in capacitance, and thus producing a corresponding small voltage change.This voltage is then converted into a 0-5V voltage, which is accepted by the data acquisition device after A/D conversion and sent to the main control chip.
