摘要

•A system based on sensor array and cloud platform is developed for real-time indoor environment occupied situation detection.•All-subsets regression model is used for sensor contribution evaluation and realized the sensor array size reduction.•Unoccupied, normally and abnormally occupied situation can be precisely classified by WV-ELM with a precision of 97.32%.
