\ \

\ \ Module description\ \ 1 It can detect the sound intensity of the surrounding environment. Note: This sensor can only recognize the presence or absence of sound (according to the vibration principle). It cannot recognize the sound size or the sound of a specific frequency.\ \ 2 Sensitivity adjustable (blue digital potentiometer adjustment in the figure)\ \ 3 working voltage 3.3V-5V\ \ 5 Output form Digital digital output (0 and 1 high and low level)\ \ 6 Fixed bolt holes for easy installation\ \ 7 small board PCB size: 3.4cm * 1.6cm\ \ \ \ Two module interface description (4-wire system)\ \ 1 VCC external 3.3V-5V voltage (can be directly connected to 5v microcontroller and 3.3v microcontroller)\ \ 2 GND external GND\ \ 3 DO small board digital output interface (0 and 1)\ \ \ \ Three instructions for use\ \ 1 The sound module is sensitive to ambient sound intensity and is generally used to detect the sound intensity of the surrounding environment.\ \ 2 When the ambient sound intensity reaches the set threshold, the DO port outputs a high level. When the ambient sound intensity exceeds the set threshold, the module D0 outputs a low level;\ \ 3 small-plate digital output D0 can be directly connected with the single-chip microcomputer, and the high-low level is detected by the single-chip microcomputer, thereby detecting the sound of the environment;\ \ 4 Small-plate digital output DO can directly drive the relay module, which can form a voice-activated switch; When there is sound, you can drive the light to light or drive a motor to rotate...\ \ \ \
