I'm actually using a wireless sensor module...
And erm, mr Mickster, to whom are u addressing that STFU?
Are you just trying to measure current used by the device, or the current used by individual components in the device? What is the purpose of this measurement?
I'm trying to measure current used by the device. The purpose is to record the power consumption of the device.
And by the way, thanks for the explanation Mickster.
