Project proposed during the course of Embedded Computer Systems Project (1001538), offered by the Department of Computing at UFSCar in semester 2022/1.

With fingerprint access control, you use a fingerprint scanner to create a template for each person you want to authorise for access. Then when they present their finger at a fingerprint reader, for example by a door, it’s compared with the stored template in your database. If it’s a match, they’re given access.

• 1 x Raspberry Pi 3
• 1 x FPM10A (50 DY) Optical Fingerprint sensor
• 1 x Relay
• 1 x Buzzer
• 1 x USB / Serial - UART converter
