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...\
