Whadda WPSE309 Microphone Sound Sensor Module

The Whadda WPSE309 high sensitivity sound detection module detects sounds between 48 and 66 dB and has an analog as well as a digital output.

The AO or analog output creates a real-time output voltage signal of the microphone, whereas the DO or digital output depends on the sound intensity and the threshold that has been set.
