How To Access Sensor Data from a Polar H10 Strap Over IoT & Compare it to Sensor Data from an Equivital Sensor Belt in Real-Time?

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 …
