Here we have a YouTube video from RobShala from India using the DF robot gravitiy optical heart rate sensor with Node MCU:
- in which he connects it to the Blink IoT Android application.
- He installs some of the libraries to his Arduino
- he uses the DF Robot heart rate library
- and a 5 volt power supply
- he shows an example which shows the heart rate without needing a PPG or ECG toolbox
- we have shown in our journal, that ESP32 can easily be connected to Home Assistant.
