It outputs a clean digital signal when vibration exceeds a set threshold, making it easy to integrate with microcontrollers for security alarms, tap detection, and activity monitoring. Its onboard potentiometer allows precise sensitivity adjustment for various applications.\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 – 5V DC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Type\u003c\/td\u003e\n\u003ctd\u003eDigital (active low)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSensitivity Adjustment\u003c\/td\u003e\n\u003ctd\u003eYes, via onboard potentiometer\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInterface\u003c\/td\u003e\n\u003ctd\u003e3-pin (VCC, GND, DO)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e32 mm × 14 mm\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\u003e\u003ca href=\"\/products\/kit-motion-alarm\"\u003eMotion-activated alarm system\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003eTap-sensitive control panel\u003c\/li\u003e\n\u003cli\u003eSeismic or impact detection logger\u003c\/li\u003e\n\u003cli\u003eSmart wearable activity tracker\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eCompatibility\u003c\/h2\u003e\u003cp\u003eCompatible with any 3.3V or 5V microcontroller, including Arduino Uno, Nano, ESP32, and Raspberry Pi (with level shifting for 5V tolerant pins).
