This sound detection microphone sensor module is ideal for noise detection in alarm systems, home automation and other applications where an event is triggered based on the presence or absence of sound. The module has two outputs: DO is a digital output that goes high when sound is detected and can be connected to a digital input of the microcontroller. AO is an analog output that provides a real-time output voltage signal of the microphone. LED1 turns on when power is applied to the module. LED2 lights when a sound is detected (i.e. when C goes high). The sound threshold to activate C is adjusted by the onboard potentiometer.
THIS SENSOR IS NOT A VOICE RECOGNIZER
