I’m teaching data to year 7 students, and am looking into having them monitor their heart rate throughout a period of time to look for correlations, etc. One option I’m looking at is to get a class set of heart monitors and play with that data. I’m looking for recommendations for devices that meet the following criteria:
- Wrist mounted
- Half-decent accuracy (I know this can be at odds with the above; I’m not expecting perfection, just don’t want absolute rubbish)
- Logs heart rate data (every minute or 5 minutes would be fine) for later retrieval, preferably over USB, but bluetooth is OK if USB not possible
- Fits small wrists
- Doesn’t invade your privacy (i.e. can be used without app/internet connection, doesn’t send your data to China, etc)
I’m personally using a Mi Band 4 (with a 3rd party app to prevent privacy issues), which fits the bill to some degree, but was wondering if there is something simpler out there, and preferably with a USB connector (mi band is bluetooth only).
