DFRobot Gravity: Capacitive Fingerprint Sensor features fingerprint collecting, processing, storing, and comparison integrated into an all-in-one solution. The sensor has the ID809 high-performance processor and semiconductor fingerprint sensor as its core. The sensor is equipped with built-in IDfinger6.0 fingerprint algorithms. This enables it to complete all the fingerprint recognition independently. When working with our Arduino Library, the module is able to realize functions like fingerprint registration, fingerprint deletion, etc.
