 Product Description

Adding a Arduino microphone to your project gives you the ability to detect sound. Whether it’s clapping, talking, shouting, or even a pin dropping the KY037 electret microphone breakout board will detect it. The KY037 Arduino compatible microphone features a built in electret microphone, high sensitivity amplifier and adjustable potometer for sensitivity tuning. This Arduino compatible sensor also features two outputs: Analog output (AO) which outputs real time voltage signal changes and a Digital output (DO) which outputs a high or low signal when the sound intensity reaches a threshold limit. Paired with the starter Arduino Microphone Code provided below you will be well on you way to developing cool new sound detection projects that will have everyone shouting about! The sensor come fully assembled, features a 3 mm mounting hole and operates at 5V with a built in indicator LED.
