{"title":"Sound Detection and Microphone Module","handle":"sound-detection-and-microphone-module","url":"/products/sound-detection-and-microphone-module","description":"This sound detection and microphone module provides both analogue and digital outputs for detecting sound with a microcontroller. The analogue output (AO) delivers a real-time voltage signal proportional to sound intensity, while the digital output (DO) triggers high or low based on an adjustable threshold set via the on-board potentiometer.\n\nCompatible with Arduino and other 5V microcontrollers, it's a straightforward way to add sound detection or audio-level sensing to your project.\n\nKey Features\n\n\nDual Output – Analogue (AO) for real-time audio level, digital (DO) for threshold detection\n\nAdjustable Threshold – On-board potentiometer sets the digital trigger level\n\nHigh-Sensitivity Microphone – Detects voice, claps, knocks, and ambient sound\n\nPower Indicator LED – Shows when the module is powered\n\nComparator Output LED – Lights up when sound exceeds the set threshold\n\n3 mm Mounting Hole – Easy to secure in enclosures and projects\n\n5V DC Operation – Standard supply voltage for Arduino and similar boards\n\n\nIdeal For\n\nSound-activated lighting and effects\nClap or knock detection switches\nNoise-level monitoring\nArduino and micro:bit audio projects\n","vendor":"Little Bird","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":5928,"title":"Default Title","sku":"LB-LR0003","price":7.58,"on_sale":false,"in_stock":true,"available_quantity":72,"option1":"Default Title"}]}
