The Internet of Things (IoT) is a network of physical objects "things" embedded with sensors, software, and other technologies for the purpose of connecting and exchanging data with other devices and systems via the internet. This project enables us to assess a seated person's posture in real time and improve sitting posture. Long-term sitting harms the spine and causes chronic problems that require long-term therapy. People who are sick have a significant impact on office productivity. Long periods of sitting while studying cause major postural and spinal problems in young people. Our motivation is to assist people in paying attention to their health and proper sitting .Maintaining good posture by sitting with a straight back and shoulders not only enhances physical well-being but also enhances confidence and productivity through the development of healthy habits and frequent breaks. To make the chair smart, we use an IoT system with sensors, processing power, and software, with the goal of eventually assisting humans in maintaining good posture and healthy habits. Making a regular chair into a smart chair using Raspberry Pi, which will continuously detect your sitting posture and send a notification if it is incorrect. Two FSR sensors will be fitted onto the backrest of the chair to detect the inclination of the chair. The backrest sensor will detect if the person is sitting straight or not. The humidity and temperature sensor module inside the cushion of the seat will detect the temperature and pressure of the user. The goal of this project is to maintain proper posture for improved health and longevity.

There are thousands of vehicles on road these days and managing these multiple vehicles at a toll booth at the same time is a very difficult job to be done. At present, the manual toll system is very inefficient and very time-consuming. Due to this, there are traffic jams, fights, exchanges of words also. The system proposed is completely managed on the ‘Internet of Things’ concept based on RFID technology. The Internet server will store all the users ' required data and their card balance. When the car driver will arrive at the toll booth, the system at the toll booth will scan the card. The system then connects to the online server to check the validation of the card, if the card is valid and will be having sufficient funds then the particular amount will get deduced from the card. The system operates a motor to open the toll gate for a car to pass on deduction of the card balance. The entire system uses a microcontroller to achieve this purpose. The WiFi connection connects to the internet through which the system interacts for online verification. Additionally, all the data of the vehicles passed will get stored for later reference. Thus, the system automates the entire process of the toll booth and terminates the present process of the toll booth collection system.
