I need a current sensor for MPPT based charge controller of max 10A current flowing.
Since the controller shouldn't be expensive, I don't want dedicated current sensors. So I have 2 alternatives:
1) Measuring voltage across Rsense using Op-amp.
2) Measuring voltage across Rsense by ADC of microcontroller.
I was wondered why no one is talking about using micro-controller for current sensing.
Upto now I plan to go for option 2. But please if there are certain things I must consider or if you have a better option, please suggest.
