Analog microphone module based on LM358 amplifier and electret mic that outputs a voltage proportional to ambient sound intensity. Connects via Grove connector; read with any ADC-capable microcontroller.
Grove Sound Sensor analogue output; Seeed wiki connects the module to analog port A0 and reads the sound level
not connected on the Grove connector; Seeed wiki code comment lists SIG,NC,VCC,GND
