Introduction
Looking for easy way to add heart rate sensor to my bike computer i have decided in august to buy mi band 2, now it is time to say a few words.
Details
Design, quality, energy efficiency are impressive, application is working quite well on both Iphone and android. I was wery interested if it can be used to monitor heart rate during mtb trainings. After many trials conclusion is as follow:1. Optical measurment of heart rate when riding a bike is not working at all, band registered heart rate 80-90 in average whailst I had my hrmax - over 180 :(
2. Accuracy of distance measurement when walking is so so, error rate is over 20%
All other features are working fine, so if you need band to monitor you body and activity during sleep, walk or joghing just buy it. For intensive trainings and precise measurrment it is usles.
