Microphone Sound Sensor Voice Detection Module with Digital and Analog

Great Sensors for Project. Having Fun With Electronics and Programming!

Description:

1. The Sound Detector is based on a microphone and a power amplifier. It can be used for detecting the sound strength of the environment.
2. This sound sensor gets signal by both digital and analog output.
3. "AO" outputs real-time voltage signal of the microphone.
4. "DO" outputs low and high lever signal when the sound intensity reaches a threshold.
5. Sensitivity is adjustable by adjusting the potentiometer.
6. PCB-mounted LEDs indicate the power and compactor output.
