Arduino Nano Datalogger and Current Sensing. Monitor up to six different voltage signals, two of which can receive a voltage signal from the two onboard current sense modules. Pass-through USB hardware is included to allow for USB VCC current sensing. All analog channels can either measure from 0-5V or 0-15V. The two current sense modules output a 0-10V signal proportional to the sensed current, up to 2A. This signal can be sent to the analog channels to be datalogged. The Arduino Nano ADC reads each channel at up to 100 Hz, and scales the raw ADC values automatically depending on the channel configurations the user has set.
