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.
