Two module wiring instructions
1.VCC external 3.3V-5V voltage (can be directly connected with the 5v microcontroller and 3.3v single-chip)
2.GND external GND
3.OUT small board switch output interface (0 and 1)
Three instructions
1. Sound module is the most sensitive to the sound intensity of the environment, generally used to detect the sound intensity of the surrounding environment.
2. When the ambient sound intensity reaches the set threshold, the OUT output high level, when the external ambient sound intensity exceeds the set threshold, the module OUT output low;
3. Small board digital output OUT can be directly connected with the microcontroller, through the microcontroller to detect high and low levels, which to detect the sound of the environment;
