Abstract: Energy efficiency of green buildings are improving its performance using Internet-of Things (IoT) based automation and associated developments. Also, as solar based power generation is achieving a decentralized structure, LVDC- alone power distribution improves efficiency and quality of power. Combining Green buildings, LVDC and IoT seems to be the future in energy management. An LVDC and IoT managed intelligent ambient light controller is developed to monitor human occupancy and thus reduce loss. LVDC based 12v power rail is considered and are connected through publish-subscribe based MQTT IoT communication protocol. The master node measures the Ambient light and communicated to other nodes and which independently alters the attached PWM driven LEDs. Human presence is sensed using a microwave radar sensor and each node communicates its presence in MQTT. An algorithm is developed to control lighting based on ambient light and human presence.
Keywords: Green Building, IoT, LVDC, MQTT, PWM.
