1.      INTRODUCTION

Smart library management is the implementation of advanced technologies and digital systems to improve the efficiency and effectiveness of library operations. It involves the use of various digital tools and techniques such as RFID, IoT, AI, and automation to streamline the library's operations, enhance user experience, and optimize resource utilization[1][3].

With smart library management, libraries can automate their cataloging, circulation, and inventory management processes, enabling librarians to focus on more value-adding tasks such as information literacy and user engagement. The implementation of smart library management also enables libraries to offer personalized recommendations, targeted outreach, and proactive support to their users, resulting in a better user experience and increased patronage[4].

Moreover, smart library management systems can help libraries track the usage of their resources, assess their impact, and make data-driven decisions to optimize their collections and services[5]. This can lead to improved resource utilization, better decision-making, and increased cost-effectiveness[6].

In summary, smart library management is a modern approach to library operations that leverages technology to enhance user experience, and optimize resource utilization[7].

2.      ARCHITECTURE

 

Fig.1.Block diagram of Smart Library Management System

The above figure shows the architecture of the Smart Library Management System. It consists of ESP8266, Battery, RFID Module, and server that hosted the web application and it is accessible via browser on any device[8].

A.        ESP 8266 development board

ESP8266 is a highly integrated Wi-Fi microchip designed by ES press if System. It is capable of providing Wi-Fi connectivity to any embedded system, and it can be used as a standalone microcontroller with built in Wi-Fi device[9]. 

The ESP8266 microchip includes an 80MHz 32-bit Ten silica processor, 64KB of instruction RAM, and 96KB of data RAM. It also has a full Wi-Fi stack, supporting WPA/WPA2 and WEP encryption, as well as TCP/IP networking protocols. It operates on a voltage range of 2.5V to 3.6V and is available in a variety of packages, including surface-mount and through-hole versions.

The ESP8266 microchip is widely used in IoT (Internet of Things) applications, as it provides a low-cost and easy-to-implement solution for adding Wi-Fi connectivity to a wide range of devices, including sensors, home automation systems, and smart appliances. It is also popular among hobbyists and makers, as it is relatively easy to program using a variety of development tools and programming languages.

Overall, the ESP8266 microchip is a versatile and powerful solution for adding Wi-Fi connectivity to embedded systems, making it a popular choice for a wide range of applications[10].

B.         RFID Module

An RFID (Radio-Frequency Identification) reader/writer module is a device that is used to communicate with RFID tags or transponders. These modules consist of an antenna, a radio-frequency (RF) module, and a microcontroller that enables communication between the module and the host system.

The RFID reader/writer module works by sending out a radio frequency signal that is received by the RFID tag. The tag then sends back a response signal containing the data stored on the tag. The reader module then processes this data and communicates it to the host system[11].

There are different types of RFID reader/writer modules available, including low-frequency (LF), high-frequency (HF), and ultra-high-frequency (UHF) modules. LF modules operate at a frequency of 125-134 kHz, HF modules operate at 13.56 MHz, and UHF modules operate at 860-960 MHz

RFID reader/writer modules are commonly used in a variety of applications, such as inventory management, access control systems, and transportation logistics. They can be integrated into a variety of devices, such as handheld scanners, desktop readers, and embedded systems.

Overall, RFID reader/writer modules are powerful and versatile devices that enable communication with RFID tags and are widely used in various applications where identification, tracking, and monitoring of objects are required

C.        Server

The server is used to host the web application and stored the all students, all books and required information in database. Web Application can be accessed through browser by any devices. Also used a custom domain to access the web application

The MQ-5LPG sensor operates based on the principle of resistance change in response to the presence of propane gas. When propane gas is detected, the resistance of the sensor changes, and this change is used to measure the concentration of the gas in the air.

The output of the MQ-5 LPG sensor can be processed by a microcontroller or any other electronic device to determine the concentration of propane gas in the environment. The sensor typically requires a power source of 5V to operate and provides a digital or analog output signal, which can be used to trigger an alarm or display the gas concentration on a screen.

In conclusion, the MQ-5 LPG sensor is a reliable, low-cost, and widely used device for detecting the presence of propane gas.

E.         LCD display (16X2)

An LCD (Liquid Crystal Display) 16x2 display is a type of matrix display that is commonly used for displaying text-based information. It consists of a matrix of 16 columns and 2 rows of characters and is capable of displaying 32 characters time. The display is typically controlled by a micro controller or computer using a serial or parallel interface, which sends commands and data to the display to control what is displayed. Some common applications for 16 x 2 LCD displays include displaying status messages, debugging  information, and user interface elements in electronic devices such as routers, appliances, and embedded systems.
