After all the sensor path options we introduced here, we think it is not worth it to invest too much time in solutions which are more complicated than for instance a 1 lead ECG device from DF Robot, with the following instruction, which is modified from the Scott Harden Sound Card ECG, and connects the sensor to an Arduino:
Interesting would be a modifications of the circuit with an ESP32 to connect it to Home Assistant / InfluxDB wirelessly.
Since we don t code, we do not have any plans to make such an instruction real soon, altough it is attractive to us personally.
Easier is for us to focus on the physiological parameters in which we are interested the most, and use the Android apps which helps us on the easiest way to get those. Anything else could be a waist of time, as for instance connecting DF Robot modules to OpenBCI:
Although we do not know of any option which is more affordable for instance for a 8 channel EEG to be amplified with a resolution of 24 bit.
