Gravity Capacitive Fingerprint Sensor with LED Lighting

This capacitive fingerprint sensor from DFRobot captures, stores and compares fingerprints by itself. At its core are the ID809 processor and a semiconductor fingerprint sensor with the IDfinger6.0 algorithm. The module stores up to 80 fingerprints and reports the result via I2C. An LED ring around the round sensor shows the status in colour. With the Gravity adapter board it works with 3.3 V and 5 V boards such as Arduino UNO or micro:bit.

Note: The connection cable can be converted to male pins with a Dupont cable M-M, so that it also fits an Arduino UNO.

Note: The library from the library manager of the Arduino IDE is faulty. Therefore download the DFRobot_ID809_I2C library from GitHub and import it into the Arduino IDE.
