Espressif's official examples and tools for Wi-Fi Channel State Information (CSI) on ESP32-series chips, enabling non-contact wireless sensing. It includes sample applications for CSI data acquisition, indoor positioning, and human activity detection.
Use cases
- indoor positioning with wifi csi
- detect human presence without cameras
- sense breathing and motion via wifi signals
- get started with esp32 csi data collection
- build smart environment monitoring with esp32
- use wifi channel state information for activity recognition
When to choose
- you use ESP32-series hardware and want Wi-Fi sensing or CSI-based positioning
- you need vendor-supported examples and documentation for CSI on ESP32
- you want to prototype non-contact sensing without extra hardware
When to avoid
- you need CSI on non-Espressif Wi-Fi hardware
- you require production-ready, certified sensing solutions rather than examples
- your project does not involve Wi-Fi sensing at all
