IoT based occupancy detection using wireless controller in a building/workspace

Abstract

Occupancy of seats/chairs in places like cafeteria, occupancy in meeting room is a key factor in offices having thousands of employees, it is often convenient to know the number of seats occupied in cafeteria and availability of meeting room in IT companies before he/she visits. There is an IoT wave sweeping the technology arena. Internet of Things (IoT) is the amalgamation of all physical nodes using internet as medium. The nodes communicate with each other over internet and allows to control or get controlled by the click of a button. Various sensor in the market can detect occupancy of the seat and the meeting room with low cost systems. The objective of the present paper is to study number of people occupied the seats in cafeteria and displayed occupied and unoccupied seats on web browser for user information, collecting those data for some period and use the data to display seat occupancy at different points of time. The above objective is achieved using shell scripts running on linux machine used to simulate the occupancy of chairs/seats in cafeteria and occupancy of meeting rooms which is communicated to webserver via IoT.
