Board dimensions are 3.2cm x 1.4cm. Operating voltage ranges from 3.3V to 5V. Features an onboard LM393 wide voltage comparator with a driving capability exceeding 15mA. Includes integrated bolt holes for simplified installation.\u003c\/li\u003e\n         \u003cli\u003e[DIGITAL STATE DETECTION]: This module outputs a clean digital signal indicating state changes. It operates by detecting transitions from high to low, or low to high, rather than continuous movement. Integrated power and output LED indicators provide immediate visual feedback of operational status during circuit testing.\u003c\/li\u003e\n         \u003cli\u003e[ADJUSTABLE SENSITIVITY CONTROL]: Unlike fixed-rate detectors, this board features a built-in potentiometer dial. Users can manually tune the threshold to prevent false triggers from a single minor bump. The normally closed design ensures stable signal output during resting states for precise automation programming.\u003c\/li\u003e\n         \u003cli\u003e[INSTALLATION INSTRUCTIONS]: 1. Connect VCC to power supply. 2. Connect GND to ground. 3. Connect DO to your microcontroller input. 4. Mount the board with pins facing downward for optimal mechanical sensitivity. 5. Turn the potentiometer with a small screwdriver to dial in your desired detection threshold. Avoid desoldering the factory pins to maintain circuit integrity.\u003c\/li\u003e\n         \u003cli\u003e[HOME AUTOMATION APPLICATIONS]: Ideal for electronics hobbyists building custom monitoring devices. Use these boards to detect appliance activity, trigger sleep-wake functions on microcontrollers, or build entry alarms. Compatible with popular development boards for extensive maker projects and equipment integration.\u003c\/li\u003e\n  \u003c\/ul\u003e","brand":"SUUOO","offers":[{"title":"Default Title","offer_id":50651428356333,"sku":"B0GX8Z2PF5","price":118.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0324\/1050\/1164\/files\/B0GX8Z2PF5.jpg?v=1788930736","url":"https:\/\/leoforward.com\/products\/10-pack-sw-420-vibration-sensor-module-with-lm393-comparator","provider":"LeoForward AU","version":"1.0","type":"link"}
