I purchased the #4041 and #4042 ACS724 Current amplifying boards. I am trying to sense and .06 mA or 60 uA. This amperage seems to be too small to sense. I need an output voltage that can pull an Arduino pin in either direction. Is there a better board I should look at? I did not try a ‘filter’ on either of these these boards.
Unfortunately, we do not have any sensors that would be appropriate for currents that small, and do not have a recommendation for where to get one.
Thank you for your response, Claire.
