How Does The Fingerprint Sensor Work?

The enclosure of the module is dust resistant but not waterproof with ring indicator LED light controlled by command, and it has a high recognition rate and the flexibility to adapt on different conditions of human finger whether it's dry, wet, a person of different ages.
