This has become possible owing to increasing availability of broadband Internet connection at a reduced cost, availability of more devices with Wi-Fi capabilities, technology affordability at lower cost and high penetration of smart phones. This paper aims to explain the possible areas to implement the IoT applications in libraries. It also implies the merits, demerits and limitations of IoT applications in the libraries.
