A sound sensor is a module that detects sound waves based on their intensity and converts them into electrical signals.
The sound detection sensor module for Arduino determines if sound levels exceed a predefined threshold. Sound is captured by a microphone and processed by an LM393 op-amp. The threshold level can be adjusted using an onboard potentiometer. When the sound level surpasses this threshold, an LED on the module lights up, and the output signal goes low.
