We presented various projects about how to access heart rate sensor data over IoT on this site. But how shall we proceed if we want for instance to make a scientific study to compare the accuracy of a Polar H10 chest strap to an Adinstruments Equvital sensor belt?
Assuming that an Institute can lend an Equitival Sensor belt from the United States Army Research Institute of Environmental Medicine to perform such as study. How can we compare the sensor data from these two devices? Garmin Connect for instance does not allow to compare sensor data from a Polar H10 chest strap and an Equvital sensor belt.
Balena offers many options for sensor data processing and vizualisations:
Here we presented two pathways to get sensor data from a Garmin watch or a Polar H10 into a Cloud service:
The following options allow us to download a Raperri PI image, flash it to a Rasperri Pi, and send the sensor data from a Polar H10 chest strap to a Balena cloud:

Your first ten devices in the Balena Cloud are always free and full-featured:
So why not to start with this Baleno project to get familiar with IoT and Bluetooth Low Energy Sports sensors? Once in a Balena Cloud, we can look where we can go from there.
An Equivital Sensor offers sensor streaming to the Blackghost software, if we have an Equivital sensor belt from Equivital and the Balckghost software:
If we have an Equivital sensor belt and the Adinstruments LabChart software, whe can process sensor data in Adinstruments LabChart Software. But how do we compare the sensor data to from a Equivital Sensor Belt to our Polar H10 chest strap?
Adinstruments LabChart software can connect to Matlab in real-time. In Matlab it is possible to do many things. We are convinced that there is a sensor pathway to Balena. For an accuracy study which compare sensor data from a Polar H10 chest strap to an Equivital sensor belt, it is probably easier to do an offline calculation. But if we want to do a real-time comparison, this are pathways which we can choose.
