It uses an LM393 comparator and a spring-based vibration switch to provide a clean digital HIGH\/LOW signal when vibration exceeds the adjustable threshold. This module is ideal for alarm systems, impact detection, and interactive DIY projects with microcontrollers like Arduino.\u003c\/p\u003e\u003ch2\u003eKey Specifications\u003c\/h2\u003e\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 to 5V DC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Type\u003c\/td\u003e\n\u003ctd\u003eDigital (HIGH when idle, LOW when vibration detected)\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\u003eComparator Chip\u003c\/td\u003e\n\u003ctd\u003eLM393\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIndicator LEDs\u003c\/td\u003e\n\u003ctd\u003ePower (red) and Signal (green)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003eapprox. 3.2cm x 1.4cm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch2\u003eWhat You Can Build With This\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eTap-activated LED lighting\u003c\/li\u003e\n\u003cli\u003eEarthquake detector prototype\u003c\/li\u003e\n\u003cli\u003eAnti-theft alarm system\u003c\/li\u003e\n\u003cli\u003eVibration feedback game controller\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eCompatibility\u003c\/h2\u003e\u003cp\u003eThis sensor module works with any microcontroller supporting 3.3V or 5V logic, including Arduino Uno, Nano, Mega, ESP32, and Raspberry Pi Pico. It connects to a digital GPIO pin and requires no additional hardware for basic operation. The onboard potentiometer allows fine-tuning for different vibration levels.\u003c\/p\u003e\u003ch2\u003eWiring Notes\u003c\/h2\u003e\u003cp\u003eConnect VCC to 3.3V or 5V, GND to ground, and DO to a digital input pin on your microcontroller. The module outputs a digital HIGH normally and pulls the signal line LOW when vibrations exceed the set threshold. No external pull-up resistors are required for stable operation.\u003c\/p\u003e\u003ch2\u003eWhy Buy from Compoden\u003c\/h2\u003e\u003cp\u003eEvery component is sourced from verified suppliers and tested for compatibility before listing.

Connect the DO pin to any digital input and use digitalRead() to detect vibrations.\u003c\/p\u003e\u003c\/details\u003e\u003cdetails\u003e\u003csummary\u003eHow sensitive is this vibration sensor?\u003c\/summary\u003e\u003cp\u003eSensitivity is adjustable via the onboard potentiometer. Turn clockwise to increase sensitivity for faint vibrations or counterclockwise to require stronger shocks to trigger.\u003c\/p\u003e\u003c\/details\u003e\u003cdetails\u003e\u003csummary\u003eDoes this sensor detect continuous vibration or just shocks?\u003c\/summary\u003e\u003cp\u003eIt detects both shocks and continuous vibration. The spring-based switch closes upon movement, and the comparator holds the output LOW as long as vibration persists above the threshold.\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.
