Development of IoT Enabled Energy Saving Smart Lighting and HVAC System for Building Environment

Abstract

Most of the appliances used in office buildings such as the room lights, fans and Air Conditioners (AC) are manually operated, where one has to switch ON and OFF these appliances. If one tends to forget to turn OFF these switches, it will impose a major challenge in building economic stimulus for their fiscal development. It can thereby increase the amount of energy consumed and thus increasing the electricity bills. Therefore, there is an urgent need for improvement and use of a smart lighting system. This paper introduces the energy- saving, easy-to-install, wireless and low cost IoT based smart office lighting system which is suitable for installation in the office or departmental company. It uses an infrared human motion sensor (PIR Sensor) working in coordination with other sensors. When no one is there in the space, all lights, fans and Air Conditioners (AC) are turned OFF; otherwise they are turned ON to save energy. The same can be controlled via IoT and the internet. The system can easily realize energy saving and easy control of LED lighting.
