This document describes a building lighting automation system that integrates Digital Addressable Lighting Interface (DALI) devices with a wireless sensor network. Sensors such as light dependent resistors and infrared sensors detect light levels and human presence. A microcontroller receives analog sensor signals, converts them to digital, and encodes them for transmission via radio frequency to a receiver. The receiver decodes the signals and displays the output on an LCD. Relays control electrical loads like lights based on the sensor data and automate turning loads on/off to save energy. The overall goal is to remotely monitor and control building energy consumption.
