Sound Detection Module

The sound module is the most sensitive to the intensity of sound in the environment, and it is commonly used to detect the intensity of sound in the surroundings. When the module’s intensity of the sound environment does not reach a predetermined threshold, the OUT will output a high level; when the intensity of the sound from the outside environment exceeds a predetermined threshold, the OUT will output a low level. The small digital output board OUT can be directly connected to the microcontroller via a single-chip microcomputer to detect high and low levels, and thus detect the sound environment.
