This Sound Sensor Module is engineered to detect audio intensity in its surroundings, translating sound waves into readable electrical signals for your microcontroller. Utilizing a highly responsive electret condenser microphone, it easily picks up ambient noises, from human speech to handclaps, making it an essential component for any interactive electronic build.\u003c\/p\u003e\n\u003cp data-path-to-node=\"5\"\u003e \u003c\/p\u003e\n\u003ch3 data-path-to-node=\"6\"\u003e\u003cb data-path-to-node=\"6\" data-index-in-node=\"0\"\u003eDual Output Versatility (AO \u0026amp; DO)\u003c\/b\u003e\u003c\/h3\u003e\n\u003cp data-path-to-node=\"6\"\u003eUnlike basic sensors that only offer a binary on\/off state, this module features dual signal outputs to suit diverse engineering needs. The \u003cb data-path-to-node=\"6\" data-index-in-node=\"174\"\u003eAnalog Output (AO)\u003c\/b\u003e provides a real-time, continuous voltage signal that directly mirrors the microphone's audio waveform, ideal for granular noise level monitoring. Simultaneously, the \u003cb data-path-to-node=\"6\" data-index-in-node=\"359\"\u003eDigital Output (DO)\u003c\/b\u003e delivers a clear High\/Low logic level when the sound exceeds a specific limit, perfect for triggering immediate actions like turning on a relay or lighting an LED.\u003c\/p\u003e\n\u003cp data-path-to-node=\"6\"\u003e \u003c\/p\u003e\n\u003ch3 data-path-to-node=\"7\"\u003e\u003cb data-path-to-node=\"7\" data-index-in-node=\"0\"\u003eAdjustable Sensitivity for Custom Thresholds\u003c\/b\u003e\u003c\/h3\u003e\n\u003cp data-path-to-node=\"7\"\u003eAvoid false alarms caused by background noise. The onboard precision potentiometer allows you to manually calibrate the digital output's threshold. By simply turning the screw, you can fine-tune the exact decibel level required to flip the DO pin, giving you complete control over your project's responsiveness.\u003c\/p\u003e\n\u003cp data-path-to-node=\"7\"\u003e \u003c\/p\u003e\n\u003ch3 data-path-to-node=\"8\"\u003e\u003cb data-path-to-node=\"8\" data-index-in-node=\"0\"\u003eSeamless Microcontroller Integration\u003c\/b\u003e\u003c\/h3\u003e\n\u003cp data-path-to-node=\"8\"\u003eDesigned for broad compatibility, this module operates efficiently on a wide voltage range of 3V to 5.5V DC. This makes it a seamless plug-and-play addition for both 3.3V systems (like Raspberry Pi or ESP32) and standard 5V logic boards (like Arduino Uno). Combined with a standard 3mm mounting hole, integration into custom 3D-printed enclosures or standard chassis is fast and secure.\u003c\/p\u003e","brand":"Sun Cheong Computer Company Limited","offers":[{"title":"Default Title","offer_id":47583929565335,"sku":"21PS001796","price":103.0,"currency_code":"TWD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0440\/4022\/4919\/files\/sound-sensor-module-top-view.jpg?v=1774951939","url":"https:\/\/scccltd.com\/en-tw\/products\/sound-sensor-module-analog-digital","provider":"Sun Cheong Computer Company Limited","version":"1.0","type":"link"}
