This project presents a solution to maximise energy savings from corridor lighting by providing on-demand, zone-based luminance in corridors. Light dimming by pulse-width modulation further increases energy savings. The designed smart lighting system utilizes a low-cost microcontroller and several types of sensors. Motion sensor is the most commonly used occupancy detector in many existing smart lighting systems, but its major flaw is false triggering due to high sensitivity to surrounding changes. Reduction of motion sensor false triggering is achieved by incorporating a secondary digital sound sensor.
