I'm currently facing the same problem. I've already run some tests and it seems quite difficult to correlate the voltage with the real consumption even having a battery model.
Does TinyOS provide any energy profiling mechanism that measures where energy is spent, and how much energy that is consumed? This is becoming extremely important for us when optimizing for low-power operation BR, Davide On 17 Sep 2012, at 17:53, Han Bin wrote: > > Dear all, > > I'm working on deploying a network of 30 telosb sensor nodes.
