{"title":"Gravity: Capacitive Fingerprint Sensor","handle":"gravity-capacitive-fingerprint-sensor","url":"/products/gravity-capacitive-fingerprint-sensor","description":"A capacitive fingerprint sensor with integrated processing, storage, and matching built around the ID809 high-performance processor and IDfinger6.0 algorithm. The sensor handles all fingerprint recognition independently — registration, deletion, and verification — without external processing. Supports 360-degree fingerprint entry and self-learning to improve accuracy over time.\n\nEquipped with the Gravity interface for easy connection via I2C, compatible with 3.3V and 5V controllers including Arduino UNO and micro:bit. Features a CNC metal ring with round breathing LED indicator.\n\nKey Features\n\n\nAll-in-One Processing – Integrated fingerprint collection, processing, storage, and matching\n\n360° Entry – Fingerprint registration and matching from any angle\n\nSelf-Learning – Improves recognition accuracy with repeated use\n\nGravity I2C Interface – Plug-and-play with Arduino UNO, micro:bit, and more\n\n3.3V and 5V Compatible – Works with a wide range of controllers\n\nBreathing LED – Visual status indicator with CNC metal ring\n\n\nSpecifications\n\n\nProcessor – ID809\n\nAlgorithm – IDfinger6.0\n\nOperating Voltage – 3.3–5V\n\nOperating Current – < 60mA\n\nCommunication – I2C (Gravity interface)\n\nStorage Capacity – 80 fingerprints\n\nVerification Time – 300–400ms (1:1)\n\nResolution – 508 DPI (160 × 160 pixels)\n\nDetection Area – 8.0 × 8.0mm\n\nSensor Dimensions – 21mm diameter × 5mm height\n\nAdapter Dimensions – 22.5 × 32mm\n\nOperating Temperature – -40°C to 60°C\n\n\nIdeal For\n\nFingerprint door locks\nDrawer and cabinet locks\nIdentity verification systems\nAccess control and authorisation\n\n\nResources\n\nProduct Wiki\n","vendor":"DFRobot","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":3506,"title":"Default Title","sku":"DF-SEN0359","price":42.17,"on_sale":false,"in_stock":true,"available_quantity":36,"option1":"Default Title"}]}
