Overview
The Fingerprint Sensor with Two-Colour LED Ring (GROW R503) is a capacitive fingerprint sensor module scanner with a two-colour ring indicator from Hangzhou Grow Technology Co. Ltd. Designed with the intention to be used as an extension of development boards and placed remotely on Fingerprint 3 Click Board™. The module is designed in a circular shape with a diameter of 28mm. It's important to mention that this module represents an integrated image collecting and algorithm chip together.
If you are interested in a more complete solution we have also created a Fingerprint 3 Click Bundle for you.
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.
