I am working on an Arduino based Blood Glucose Meter. My sensor gives a current value proportional to the glucose concentration, which I need to send to the Arduino for processing. The current value is in the range of uA.
I'm aware that I'll have to convert this current value into a suitable voltage value for the Arduino, and based on my research an approach to do this is to use an opamp as a current to voltage converter.
Which opamp should I use for my application? I read that since the Arduino operates on 5V, I won't be able to use the LM741 since it operates from -15V to +15V.
