I'm currently working on a project and I need to log the current(in microamperes) induced on a coil. The main idea is to log the data on small time intervals, that is, 0.5 or 1 sec. and I want a plot of current vs. time. The computer that I use will be always open, and after each 24 hours, I will take a report of the measured values. As I expressed above, the current's unit will be on microamperes scale, and its sign would be positive or negative. Which product(s) would be the most suitable for my purpose?
