Here an example with from RobSala in India where he connects an optical heart rate monitor to ESP32:
Here an example with from How to Electronics in India where he connects an ECG heart rate monitor to ESP32:
The main components are the sensors, an ESP32 module, a breadboard and wires. If we want a sampling rate for our sensors of at least 16 bit for A/D conversion, we need additionally such a module for around 2 USD.
The same thing for EEG sensors. The costs for 8 individual EEG sensors aren t much different anymore to devices with a 8 channel chip like OpenBCI, or even lower. Individual sensors can easier be connected to Home Assistant over ESP32.
We have the NeuroKit2 for physiological sensors. But is this software not developed by coders for coders? We aren t coders, and we are looking for the easiest way possible.
We do not know if there will be a simple platform for physiological sensor in Home Assistant. This is eventually not necessary. A good starting point for beginners is the instruction from Udo Berndt from smart-live.net which shows how to visualize Apple watch data in Home Assistant:
