fitbit v2

As promised in the previous post, I made another attempt at getting more accurate readings from the fitbit. The good news is that wearing it tighter does seem to improve the sensor readings. The bad news is that I'm not sure if this tightness is comfortable in the long run, we'll see.

The following was recorded while grocery shopping, cooking and eating Salmon Teriyaki bowls and some reading:

The two peaks in heart rate correspond to me walking to and from the grocery shop. Curiously the fitbit once again exaggerated my actual pulse; this time though there was definitely no stray light (I wore the fitbit tight against the skin, under a long sleeved shirt and a coat).

I'll perform some more experiments tomorrow with wearing the fitbit in reverse, i.e. with the sensor against the bottom of my arm.
