KY-038 LM393 Sound Detection Sensor Module for Arduino detects whether the sound has exceeded a threshold value. The sound is detected via a microphone and fed into an LM393 op-amp. The sound level setpoint is adjusted via an onboard potentiometer. When the sound level exceeds the setpoint, an LED on the module is illuminated and the output is sent low.

Digital amplifier board has a higher overload capacity than the analog amplifier, and it won’t cause crossover distortion, This is an audio power amplifier board that strengthens low-power, inaudible electronic audio signals such as the signal from radio receiver or electric guitar pickup to a level that is strong enough for driving loudspeakers or headphones. Power amplifiers make the signal audible to listeners. This audio amp board is the final electronic stage in a typical audio playback chain before the signal is sent to the loudspeakers and speaker enclosures.
