Hi,
My tmote's worked until 1.8 V, but with this voltage temperature gives
strange values. ;)
Regarding to this topic, I'm working in reducing some power consumption,
Is there any way to know the actual consumption in mA of the tmote sky?
the idea is to check if implemented improvements really save energy.
Thanks
Xavi

You are correct about battery energy, but note the minimum voltage for
the AA
cells you are using. At 2.1v, each cell is providing 1.05v, which is at or
near the 'end voltage' for many chemistries. I wouldn't be surprised if
the
energy cost of additional power conditioning (the parts would draw power
themselves) exceeds what little extra you can scavenge out of the cells.
Best,
Steve
