Introduction
The Smart Home system is an RFID access control and automated system that will provide ID-based entry into a building and trigger the activation of a user-matched
This system will use an RFID authentication mechanism to communicate with a microcontroller that will release an electric door strike for access and turn on a set of lights corresponding to the pre-determined path of the user
What is RFID
A basic RFID system consists of three components:
-An antenna or coil
- A transceiver (with decoder)
- A transponder (RF tag)
Electronically programmed with unique information. There are many different types of RFID systems out in the market. They are categorized according to their frequency ranges. Some of the most commonly used RFID kits are as follows:
Low-frequency (30 KHz to 500 KHz)
Mid-Frequency (900KHz to 1500MHz)
High Frequency (2.4GHz to 2.5GHz
Conclusion
RFID technology is taking off in libraries at an increasingly rapid pace. Though there are few libraries employing this technology today, but due to its customizable feature and continuing improvement the library communities are beginning to get involved in its development. It is easy to envision that, the RFID tags contents will increase in power, prices are expected to decline and tag will dramatically improve its efficiency, security and accuracy. Also major concerns need to be addressed for successfully implementing this technology. So that it will change our personal and work lives in library and adorns the conventional library management with a new idea and usher for a bright future.
