Time clock system using fingerprint sensor and NTP

Description:

This project is Time clock system using fingerprint and Network Time Protocol via ethernet along with use of WIZwiki-W7500.

Hardware components:

1. GT-511C3(Fingerprint sensor module)
2. WIZnet WIZwiki-W7500

1. System Architecture

2. FingerPrint sensor module

Model : GT-511C3

CPU: ARM Cortex-M3

Maximum number of saving fingerprint: 200

Communication: UART

Support window program

Window program

GT-511C3

3.Enroll ID

• By window program

• By UART Command

If you push the button linked D8 pin and then WIZwiki-W7500 is booted, enroll function is called.

4.Delete ID

– By window program

-You can delete one ID or all

– By UART command

If you push the button linked D7 pin and then WIZwiki-W7500 is booted, delete all function is called.
