Sound sensor module

The sound sensor module for Arduino detects whether the sound has exceeded a threshold value. Sound is detected via 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. Technical Specifications
