Introduction

The sound sonser module is sensible to the instensity of sound, therfore, it’s widely used in detecting the instensity of sound of surrouding. When the sound instensity is lower than the threshold value, the module output logic high, oppositely, when the sound instensity is higer than the threshold value, the module output logic low.

Technical data

Work voltage: 3.3 to 5V

DO: output logic high or low
