Main function this project was build as part of a network communications class at universidade do algarve in collaboration with my colleague luís santos.
Wifi rfid door lock.
Here we will make a smart rfid door lock by using arduino and ultrasonic sensor.
Many businesses use radio frequency identification rfid door locks.
Its main purpose is to control the access of an electric lock through wireless with the.
When the card comes within a few feet of the reader s antenna the rfid chip transmits its data identifying the user to a security computer.
I hope you guys enjoy learning this project.
Once connected via some type of communication technology wi fi bluetooth zigbee z wave a smart lock can connect either to your smart phone smart home hub or your internet router to allow you to access your door in new ways.
Arduino codes and library.
Each key card contains data encoded on a machine readable rfid chip and plays an integral part in a computerized security system.
