Apple watch series 6 ppg sensor data


My middle schooler is working on a project for National Science Fair competition to estimate blood pressure from ppg signals. While he is using external database to develop his algorithm, it would be very useful to test it with real time data. I have a Series 6 watch and wondering how I can access my ppg sensor raw data.

You can use HealthKit and have your app request access to the Blood Oxygen data (HKQuantityTypeIdentifierOxygenSaturation)

You can find out more about the HealthKit framework here:

Sharko33 were you ever able to access the raw ppg data? I have a similiar interest.
