The Use of RFID Sensors for Automatic Doorstop Application

Abstract

RFID or Radio Frequency Identification, is the process of identifying a person or object to the use of radio transmission frequency. RFID is a method which can be used to store or receive data remotely by using a device called RFID tags or transponders. Transponders that be used is a passive transponder that have limited power capacity, so it can only stores data that is generally a course ID number. Example of passive transponder is the e-ID card. In the e-ID card and chip antennas are used to capture the radio waves emitted by the RFID reader, and IC is used to store information. The application of RFID will be placed on an automatic doorstop where to open the e-ID card is used that has been registered in the database system. This tool is also equipped with sensors HC-SR04 as the cover latch automatically. The automatic latch uses a microcontroller atmega 328 (arduino) as the brain of this tool. Factor of safety, automation, and time efficiency into consideration for making this final task, where the use of the identification system is needed.
