The KY-037 microphone sensor module acts as the \"ears\" of your microcontroller, engineered to pick up ambient noise and translate it into a readable electronic signal.\u003c\/p\u003e\n\u003cp data-path-to-node=\"7\"\u003eBuilt with a highly sensitive electret condenser microphone, it is designed for rapid response. It detects sound waves up to 0.5 meters away, making it the perfect component for localized audio triggers.\u003c\/p\u003e\n\u003cp data-path-to-node=\"7\"\u003e \u003c\/p\u003e\n\u003ch3 data-path-to-node=\"8\"\u003eDual Output Flexibility (Digital \u0026amp; Analog)\u003c\/h3\u003e\n\u003cp data-path-to-node=\"9\"\u003eThis module doesn't just limit you to a simple on\/off switch. It features a versatile 4-pin interface that provides both digital (DO) and analog (AO) outputs:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli data-path-to-node=\"10,0,0\"\u003e\n\u003cb data-path-to-node=\"10,0,0\" data-index-in-node=\"0\"\u003eDigital Output (DO):\u003c\/b\u003e Outputs a simple high\/low signal when the sound volume crosses a specific threshold. Perfect for triggering relays, LEDs, or simple microcontroller interrupts.\u003c\/li\u003e\n\u003cli data-path-to-node=\"10,1,0\"\u003e\n\u003cb data-path-to-node=\"10,1,0\" data-index-in-node=\"0\"\u003eAnalog Output (AO):\u003c\/b\u003e Provides a real-time voltage representation of the microphone's audio signal, allowing you to measure sound intensity variations dynamically.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3 data-path-to-node=\"11\"\u003ePrecision Control with Onboard Potentiometer\u003c\/h3\u003e\n\u003cp data-path-to-node=\"12\"\u003eStop guessing and start tuning. The integrated VR1 potentiometer allows you to fine-tune the digital output's threshold sensitivity. A simple twist with a screwdriver lets you calibrate the sensor to ignore background hums and only trigger upon distinct noises, such as a handclap or a breaking glass sound.\u003c\/p\u003e\n\u003cp data-path-to-node=\"12\"\u003e \u003c\/p\u003e\n\u003ch3 data-path-to-node=\"13\"\u003eReliable LM393 Comparator Architecture\u003c\/h3\u003e\n\u003cp data-path-to-node=\"14\"\u003eAt the heart of the KY-037 is the industry-standard LM393 comparator chip. This ensures the digital output signal is crisp, stable, and free from the jitter that plagues lower-quality sensors. Coupled with built-in LED indicators for power and digital output status, troubleshooting your circuit board logic has never been easier.\u003c\/p\u003e","brand":"Sun Cheong Computer Company Limited","offers":[{"title":"Default Title","offer_id":47722489708695,"sku":"21PS001112","price":20.0,"currency_code":"HKD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0440\/4022\/4919\/files\/ky-037-sound-sensor-module-main.jpg?v=1777097023","url":"https:\/\/scccltd.com\/products\/ky-037-high-sensitivity-sound-sensor-module","provider":"Sun Cheong Computer Company Limited","version":"1.0","type":"link"}
