Could you build this?
No Extracting and interpreting Channel State Information (CSI) from Wi-Fi frames for motion detection requires low-level embedded ESP32 programming and specialized RF signal processing.
What it would actually take: The stack requires ESP-IDF in C/C++ configuring the ESP32 Wi-Fi hardware to capture raw 802.11 CSI subcarrier data packets. The hard part is filtering hardware noise, multipath interference, and phase shifts using digital signal processing algorithms (e.g., Butterworth filtering, PCA, or Doppler analysis) to reliably classify human motion. This demands deep domain expertise in radio frequency communications and embedded DSP.
