Abstract
A method includes obtaining wireless fidelity (Wi-Fi) based channel state information (CSI). The method also includes filtering the CSI to remove radio frequency (RF) interference. The method further includes executing a motion detection module that detects for motion in a space based on whether macro-movements are present in the filtered CSI, and provides an indication that the space is occupied upon detecting motion in the space. The method also includes, in response to the indication that the space is occupied, executing an occupancy detection module that detects whether the space is still occupied based on whether micro-movements and breath signals are present in the filtered CSI, retains the indication that the space is occupied upon detecting that the space is still occupied, and provides an indication that the space is not occupied upon detecting that the space is no longer occupied.
