If physiological multi-sensor devices based on InfluxDB still too complicated for us, let us build a device based on the AD8232 ECG chip, the ADS1115 16 bit A/D converter & ESP32 instead

These are the building blocks for a multi-channel ECG device for medical & research grade applications:

The AD8232 ECG chip, the ADS1115 16 bit A/D converter & an Arduino microcontroller – the building blocks for a multi-channel ECG device for medical & research grade applications

And if we want to use InfluxDB later on, the ESP32 is easy to connect to software platforms based on InfluxDB.
