Innovation Summary: A sensor fusion system combines multiple low-power sensing modalities to detect occupancy with high accuracy. The architecture integrates passive infrared, ultrasonic, and environmental sensors, using a fusion algorithm to reduce false positives and energy consumption. The system is optimized for battery-powered and wireless applications. It supports adaptive thresholding and dynamic calibration for varying environments.
Challenges / Opportunities: Conventional occupancy sensors often rely on single modalities, leading to unreliable detection and higher power draw. This invention addresses those limitations by combining complementary sensors and intelligent processing. It opens opportunities for smart building automation, energy conservation, and scalable IoT deployment. The system is suitable for retrofit and new installations.
