The current trends and advancements in IoT have resulted in interactive, innovative and automated implementations of smart systems. The paper proposes a smart office automation system that creates an employee friendly atmosphere with the help of IoT, interconnected sensor networks and efficient database system. At the entrance, employees don’t have to manually mark their presence in the office every day. Instead of this, it gets done as soon as they enter the office using the RTLS tags without touching or standing in the queue as it prevails in most of the offices. The AC units and appliances power up automatically according to the entrance and occupancy of the employees using various sensors and interconnected network system. The owner of the company can keep a check on the resource utilization using the smart energy management sensors. Also, the employees can check the availability of meeting room and can schedule a slot for their meeting by just a click. The paper puts forward feasible, cost effective as well as resource efficient system.
