Espargos: ESP32-based WiFi sensing array
ESPARGOS is a phase-coherent, ESP32-based WiFi antenna array designed for low-cost sensing applications.
ESPARGOS provides Channel State Information (CSI) estimated from the L-LTF and HT-LTF pilot symbols in real time. Configure ESPARGOS with the built-in web interface, and then easily stream channel state information to your application in real time. The hardware design and firmware files of ESPARGOS are currently not open source, but the pyespargos library including the demo applications are free software.
