ESP32 CSI for localization / gesture recognition
Posted: Sat Jan 04, 2020 1:41 pm
Hi,
I'm looking for a solution and hopefully someone can give me an answer. I want to develop a number of edge devices where I can very accurately determine what the movements are in a room, that's how I ended up on the Atheros CSI and Linux 802.11n CSI tool. Now my search has ended on the ESP32 chip that can provide me with CSI (channel state information) data. The tools from Atheros and Linux are pretty accurate to get CSI data because they have multiple antennas, among other things.
Now I was wondering, is the ESP32 chip accurate / reliable enough to do a similar measurement like other tools with the Linux 802.11n CSI tool and is it sufficient in terms of range for gesture recognition?
As an example: If I make a number of edge devices based on the ESP32 chip and I put them throughout my house. Would I theoretically have reach through all the rooms where I put an edge device where I can get the CSI data (of course depending on the setup, etc.)
I have already looked at the following github page: https://github.com/jonathanmuller/ESP32 ... ation-CSI-
If there are people who have experimented with this before, I would also like to hear it.
Thank you so much for your helps.
