Methodology for Implementation of Building Management System Using IoT Ankita Harkare, Vasudha Potdar, Abhishek Mishra, Akshay Kekre, and Hitesh Harkare Abstract In recent times the need for automation has grown many folds. The need of the hour is to control and display the working of systems utilized in everyday life with a click of a button. This paper presents the designing and implementation of the parking management system (PMS) as a part of a building management system (BMS). Also, the paper suggests the methodology for the effective working of the building management system. The implementation of the communication protocol will be both wired and wireless for effective working. The user will be able to see the display of the status of occupancy immediately as the data will be updated through the Internet periodically. The objective is to reduce the search time required to search for any vacant slot for parking and indicating it, using red or green LED indicators and thus sending all the real-time information to a master server for monitoring purposes or to a display at the entrance. The ultrasonic parking system has been successfully checked and its design has been verified which successfully detects the presence or absence of vehicles under it and indicates it by blinking red/green LED, respec- tively. PMS is planned and strategised for interconnection using internet/intranet connectivity. Keywords Building management system · Parking management system · Internet · Automation · Ultrasonic A.
