Analog Sound Detection Sensor Module – Microphone-Based Trigger (VMA309)

Description

This 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 realtime output voltage signal of the microphone whereas the DO or digital output depends on the sound intensity and the threshold that has been set.
