Can voltage and current values be captured and logged in labview?

    I'll describe our current set up:

    We have energy being drawn from a thermoelectric module, to a resistor (just dumping it). We are acquiring the temperatures across the thermoelectric module, into labview, using thermocouples, but right now, current and voltage measurements are being done manually (using a voltmeter). Is there a product that allows you to acquire current/voltage data and send it to labview? Anything you can recommend for this current set up?

    Check out the data aquisition modules from companies like National Instruments. Their USB-based data acq modules are especially handy. For current acquisition, you'll probably need to put in a shunt (low value) resistor, and do a differential voltage measurement across the shunt.

    BTW, most of NI's data acq modules are built into LabView as drag-and-drop objects, IIRC.
