Produktbeskrivelse

Great Sensors for Project. 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 level signal when the sound intensity reaches a threshold. Sensitivity is adjustable by adjusting the potentiometer. PCB-mounted LEDs indicate the power and compact output.
