This thesis addresses the limitations of current safety alert systems<br/>that rely on wearable sensors by proposing a novel Human Activity<br/>Recognition system based on Wi-Fi Channel State Information (CSI)<br/>and designed following the Edge Computing paradigm, where data<br/>processing occurs directly on the device responsible for data collection.<br/>The research is structured in three phases.<br/>First, an Structured Literature Review (SLR) was conducted to assess<br/><br/>state-of-the-art methods for Wi-Fi CSI collection and processing, re-<br/>vealing two critical gaps: the lack of a user-friendly, high-performance<br/><br/>CSI collection tool and the absence of edge-based implementations for<br/>near real-time Wi-Fi sensing with low-cost devices.<br/>To address these gaps, this work first introduces the ESP32 CSI Web<br/>Collecting Tool, a tool for collecting Wi-Fi CSI from ESP32 devices.<br/>Experimental results demonstrate that the proposed tool outperforms<br/>existing ESP32-based solutions, achieving a packet rate of up to 85<br/>packets per second (compared to 30 packets per second in prior tools)<br/><br/>when transmitting CSI data to a computer via a USB port. Addition-<br/>ally, the tool supports local data storage via an SD card and real-time<br/><br/>transmission to external devices through GPIO pins, enhancing its<br/>versatility for edge applications.<br/><br/>Leveraging this tool, a lightweight Deep Learning model was opti-<br/>mized for deployment on the resource-constrained ESP32 microcon-<br/>troller. By considering the hardware limitations of the implemen-<br/>tation device, the model achieves an overall classification accuracy<br/><br/>of 90.65% with an inference time of 232 ms, enabling near real-time<br/>functioning at the edge.<br/><br/>The contributions of this work include a high-performance, open-<br/>source CSI collection tool for the ESP32 platform and the first known<br/><br/>implementation of an embedded system leveraging Deep Learning<br/>model for Wi-Fi HAR on an ESP32 device, which demonstrates the<br/>feasibility of near real-time, device-free safety monitoring. |
