A sound sensor is a module designed to detect sound waves based on their intensity and convert them into electrical signals. The sound detection sensor module for Arduino determines if the sound level has surpassed a specified threshold. Sound is captured by a microphone and processed by an LM393 op-amp. The sound level set point can be adjusted using an onboard potentiometer. When the sound level exceeds this set point, an LED on the module lights up, and the output signal goes low.
