emg sensor with esp32
Currently, I am working on a project to transfer data from an EMG sensor using an ESP32 to a computer wirelessly. I will use the Wi-Fi available on the ESP32. I have three ESPs, two of which will be used as slaves and one as a master to collect data from them. Then, I will send this data to the computer.
Additionally, after receiving this data on the computer, I can process and display it in Excel or plot it
I think this is long and unprofessional way to do it ... Am i right... And can u segest other ways to do so...
