When the ambient sound intensity of the module does not reach the set threshold, OUT outputs a high level. When the ambient sound intensity exceeds the set threshold, OUT outputs a low level. Using LM393 comparator output, the signal is clean, the waveform is good, and the driving ability is strong, exceeding 15mA.
