It uses an onboard electret microphone and amplifier, outputting a continuous signal ideal for real-time sound level monitoring. With a built-in sensitivity adjustment, you can fine-tune the response for whisper‑quiet or loud environments.\u003c\/p\u003e\n\n\u003ch2\u003eKey Specifications\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003eOperating Voltage\u003c\/td\u003e\n\u003ctd\u003e3.3V – 5V DC\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eOutput Type\u003c\/td\u003e\n\u003ctd\u003eAnalog voltage (0V to VCC)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eMicrophone\u003c\/td\u003e\n\u003ctd\u003eElectret condenser\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eSensitivity Adjustment\u003c\/td\u003e\n\u003ctd\u003eOnboard potentiometer\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eFrequency Response\u003c\/td\u003e\n\u003ctd\u003e50 Hz – 10 kHz (approx.)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e32 mm × 17 mm × 10 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eWhat You Can Build With This\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\u003ca href=\"\/products\/kit-sound-activated-led-kit\"\u003eSound-activated LED or relay switch\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"\/products\/voice-home-automation-kit-with-arduino-uno-and-hc-05\"\u003eVoice clap detection for home automation\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003eAmbient sound level monitor with serial output\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"\/products\/music-reactive-3d-led-sculpture-kit-with-arduino-mega\"\u003eSimple music-reactive LED visualizer\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eWorks with any microcontroller that has an analog input: Arduino Uno, Nano, Mega, ESP8266, ESP32, Raspberry Pi Pico (with ADC), and STM32. Connect VCC to 3.3V or 5V, GND to ground, and OUT to an analog pin. Logic levels match both 3.3V and 5V systems without extra level shifting.\u003c\/p\u003e\n\n\u003ch2\u003eWiring Notes\u003c\/h2\u003e\n\u003cp\u003eConnect the VCC pin to a 3.3V or 5V power rail, GND to ground, and the OUT pin directly to an analog input on your board. The analog voltage ranges from 0V in silence to nearly VCC for loud sounds. Start with the potentiometer at mid‑range; turn it to adjust output gain up or down depending on ambient noise. Avoid powering the module from a digital I\/O pin that cannot supply sufficient current.\u003c\/p\u003e\n\n\u003ch2\u003eWhy Buy from Compoden\u003c\/h2\u003e\n\u003cp\u003eEvery component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.\u003c\/p\u003e\n\n\u003cdetails\u003e\u003csummary\u003eIs this compatible with Arduino Uno?\u003c\/summary\u003e\u003cp\u003eYes, directly. Connect VCC to 5V, GND to GND, and OUT to any analog pin (e.g., A0).

To detect specific frequencies you would need a microphone module with digital I2S output and perform Fast Fourier Transform (FFT) analysis in code.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eHow do I adjust the sensitivity?\u003c\/summary\u003e\u003cp\u003eLocate the small blue potentiometer on the board. Turn it clockwise to increase output gain (more sensitive) or counterclockwise to reduce it. Adjust while monitoring the analog reading for your target noise level.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdiv class=\"compoden-handoff\" style=\"margin-top:24px;padding:16px;background:#f0f4ff;border-left:4px solid #2B4D8F;border-radius:4px;\"\u003e\n  \u003cp style=\"margin:0 0 6px 0;font-weight:600;color:#1A3560;\"\u003e📦 Free Setup Handoff Document Included\u003c\/p\u003e\n  \u003cp style=\"margin:0;font-size:0.95em;color:#333;\"\u003eEvery Compoden order includes a free setup handoff document — step-by-step instructions to get your component working within minutes.
