How Does The Fingerprint Sensor Work?
The GROW R503 Fingerprint Sensor has an image buffer and six feature file buffers. Important note for users is that all buffer contents are not saved after power failure. A fingerprint pattern template can be composed of 2-6 feature files. If the composite template has more characteristic files, the fingerprint pattern template has the better the quality. 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.
This module can be connected to existing Fingerprint 3 Click board or to any other product that has 1.0mm pitch vertical type wire to board connector as this module and the appropriate type of communication.
