I recently did some measurements of the power consumption of Mica 128 motes. Here are the numbers I got, (all the numbers the power consumption of the entire system in particular state listed below)
lower power (snooze) 0.97mA idle (with radio disabled) 4.97mA idle (with radio enabled) 11.30mA Tx (send raw RF through SpiByte) 12.90mA Rx 7.78mA
The numbers are different from the ones I found from the ones given in WSNA'02 paper. In particular to receive an AM packet consumes roughly as much energy as transmitting an AM packet (see the attached eps files). I wonder if there is anything wrong with my measurement methodology. In my experiments, I removed all unnessary components.
Thanks!
