Having Fun With Electronics and Programming! Description: The Sound Detector is based on a microphone and a power amplifier. It can be used for detecting the sound strength of the environment.This sound sensor gets signal by both digital and analog output.\"AO\" outputs real-time voltage signal of the microphone.\"DO\" outputs low and high lever signal when the sound intensity reaches a threshold.Sensitivity is adjustable by adjusting the potentiometer.PCB-mounted LEDs indicate the power and compactor output.
