[Tinyos-help] Power consumption measurement

[Anton]

Hi,

I used 10Ohm resistor connected in series between TelosB and its two AA 
batteries and measured the voltage drop with an oscilloscope Agilent 
DSO7032A:

   |                     |                                                |
   |             10 Ohm resistor                       Oscilloscope
   |                     |                                                |
   |                    +-------------------------------+
   |                     |
   |                TelosB
   |                     |
   |               batteries
   |                     |
  +-------------+


Also, when there was no need for exact current values of particular 
phases of the mote operation, I used two multimeters Agilent 34411A to 
measure the average current drain and voltage during some time interval:

  +-------------+
   |                     |
   |             multimeter (as an amperometer)
   |                     |
   |                     |
   |                     |
   |               batteries
   |                     |
   |                    +-------------+
   |                     |                     |
   |                TelosB         multimeter (as a voltmeter)
   |                     |                     |
   |                    +-------------+
   |                     |
  +-------------+
