Fingerprint Sensor With Arduino

Hello, In this article we will see how to use fingerprint sensor with Arduino. With Fingerprint sensor you can add security and lock to your home, office, garage and many more. Not only about secuity, you can add use this module where you want in time and out time in the access restricted area.
We will be using GT511C3 Fingerprint module interface with arduino.

You will need Arduino Board. You can select any of the following,

1. Arduino Nano - https://www.banggood.in/custlink/KKGygoIaOF
2. Arduino Uno - https://www.banggood.in/custlink/GvmyBlZaOo
3. Arduino Pro Mini - https://www.banggood.in/custlink/vvGy0Lijj0
4. Arduino Mega2560 - https://www.banggood.in/custlink/vKGY0lioLA

Again you will need GT511C3 module.

We will interface GT511C3 module with Arduino with UART interface.

Here is connection of the Module
