[Tinyos-help] Compute instant energy consumption

[David Rodenas]

Hi all
I wonder if there is any TinyOS component or any method to measure the instant 
energy consumption (or get the average energy consumption periodically) on the 
nodes in a real fashion (not by means of simulation tools). I am working with 
Micaz devices and the only idea that comes to my mind is using theoretical 
values from MicaZ's datasheet. However, this would be just an estimation, and 
it would take too much time to compute this information. 
All the help possible would be appreciated. Thanks in advance,

Hi David,

You can measure the voltage level of batteries (using  VoltageC component)
during a period and then make a figure with the evolution of the voltage
level over the time. After if you calculate the mean slope you get the mean
slope that means the consumption (but it's the mean consumption and not the
instant consumption).
