Good afternoon,
I want to build an arduino based current data acquisition setup. I was thinking of using a current transformer like
this one and then send the output to an arduino. I have average knowledge of electronics and programming and need your help on some points.
First of all, how hard is it to use the Arduino as a USB data input? I would only need to record data about once per minute in a CSV file. If it is too hard to implement this on the Arduino I will probably end up using something like a
Dataq.
No matter what the sensor is hooked to, its output will be a small AC voltage (<10 VRMS) and (I think) will have to be converted to DC for before being fed to the acquisiton module. What is the usual and/or simplest way to do this? The only AC -> DC conversion I ever made was a bridge of 4 diodes without even a smoothing cap and I don't know if there is a magic IC which could do a similar job and be more precise. If it matters, this module will be measuring a 60Hz electric motor.
Well that is a big part of my problem. Thank you for your help.
