We already reviewed this topic here:

How to build a physiological multi-sensor device based on InfluxDB?

to summarize the main components:

1. Start with the Apple watch:

Apple Health Daten in Home Assistant visualisieren

2. Add a temperature sensor over ESP32 to Home Assistant

3. Add an AD8232 ECG Sensor over ESP32 to Home Assistant

How to Electronics showed how to add an AD8232 ECG Sensor over ESP32 to the Ubdots cloud.

Instead of connecting this circuit to Ubudots we can try if we can connect it to Home Assistant following the example with the temperature sensor shown in the video above:

4. Add an ADS1115 chip for 16 bit analog to digital conversion rate

for research applications 16 bit analog to digital conversion rate is recommended. We can solve this problem by adding an ADS1115 chip

Here are two more instructions which use an ECG or a PPG sensor with the ADS1115 chip:

5. We can add further ECG, EEG, MEG, etc. sensor following the example of the AD8232 ECG Sensor

Home Assistant and InfluxDB are multi-sensor applications, so we can add as many sensors as we want.

6. We can test if we can read and write sensor data with the InfluxDB client for Python in Home Assistant

7. We can run Home Assistant on a Raspberry Pi for mobile applications
