Sound Sensor Module HS-S53P

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.

10, Test results

Arduino UNO test results:

After the device is connected to the line, upload the above program to the Arduino uno development board, open the serial monitor, and if the analog value of the sound sensor is greater than the set threshold (detecting sound), the LED light will be on for 2 seconds, otherwise, the LED light will be off.
