A sound sensor is a module that detects sound waves by measuring their intensity and converting them to electrical signals. The sound detection sensor module for Arduino determines whether or not a threshold value has been exceeded. A microphone detects sound and feeds it into an LM393 op-amp. An onboard potentiometer is used to adjust the sound level set point. When the sound level exceeds the threshold, an LED on the module illuminates and the output is turned off. Applications like voice switch Projects and loudness level indicator.
