The use of Radio Frequency Identification (RFID) systems in industrial technologies, health, agriculture, transportation, etc. has suddenly increased in recent days. The internet of things is flourishing.With the help of the Raspberry Pi 3 and RFID Technology, the attendance management system uses the Internet of Things to speed up the time-consuming process of documenting daily attendance in schools and other institutions. Thus, everything in this place becomes mechanised. The creation of an Android application (app) to enable students to view their attendance from any location has also been attempted.

Medical Infrastructures are viewed as a potential case in the area of improvement intended for IoT applications. The medical requirements regarding the patient is continuously monitored at any convenient place and directed to the physician spontaneously without any human intervention. As a scientific mathematical instrument, hypergraphs can be instigated to exemplify computer networks, biological networks, data structures, and various other systems. Hypergraphs are often used, to map the objects in the system and the complex relationships between them. Blockchain can be considered as a chain or records stored in the forms of blocks which are controlled by no single authority, which contains transactional records, ensuring security, transparency, and decentralization. Blockchain is completely open to everyone on the network as it is a distributed ledger. Each transaction on a blockchain is fortified with a digital signature that proves its legitimacy. While transactions take place on a blockchain, there are nodes on the network that legalize these transactions. Due to the use of encryption and digital signatures, the data stored on the blockchain is tamper-proof and cannot be transformed. In blockchain, the nodes are called as miners and they use the concept of Proof-of-work, in order to process and authorize transactions on the network. In order for a transaction to be valid, each block must refer to the hash of its preceding block. Blockchain consists of different consensus algorithms securing it from cyber-attacks.
 

There is a rising concern in designing options for elderlies residing in a society with an increased population ageing. IoT is a revolutionary phenomenon that transforms our life entirely as well as aims to revolutionize current healthcare into a more individualized, precautionary and inclusive approach to treatment. In order to integrate these two main problems, this research provides an IoT-ready approaches for elderly living treatment that can track and record critical details for patients in emergencies and include protocols for activating alarms.The strong low / low-cost / wireless capabilities make this approach into a secure and convenient wristband, perfect for anywhere and anywhere. There has been a strong device efficiency for incorporated functionalities and an overall battery life time of 306 hours (around 12 days) has been reached with respect to autonomy. Without the need of the out - of-range alarm, the device has demonstrated its output within a distance of 60 metres.

In today’s world sometimes when fire accidents occur it is difficult for the fireman to access the place of fire and extinguish it. Also it is difficult to monitor such hazards, since human beings find difficulty in accessing these places. This job could be done with the help of robots. These robots have the capability to detect and extinguish fire automatically .These robots are based on IoT and has flame sensor to detect the fire. The movement of robot is controlled by gear and motor driver. The communication is done with Arduino ATmega258 microcontroller and IoT device. The robot also has the capability to detect obstacles which comes across its path. It can send live updates to webpage by means of IoT device.

In today's world, every household is required to have a home security system installed. Before
recently, most doors could be opened using traditional methods such as keys, security cards,
passwords, or pattern locks, but this has changed. Accidents like losing a key, on the other
hand, have resulted in much more concerning scenarios such as robbery and identity theft
than the loss of a key itself. This has progressed to the point that it is now considered a major
problem. In order to overcome this problem, the development of facial recognition technology
was conducted, and the Internet of Things (IoT) was also used in the effective installation of a
door access control system. In addition to serving as the primary controller for face
recognition, the youth system, and the locking system, the Raspberry Pi is also employed as a
tiny computer board that can be programmed. The person who is standing in front of the door
is photographed with the aid of a camera, which is mounted on the wall. If the face is not
recognised by the system, a warning will be generated. Using Internet of Things (IoT)
technology, a user may control the access to a door.
