I'm looking to install thermocouples or thsrmometers around my house to monitor temperatures in each room throughout the day. I'll wire these to my pc, probably with a cheap USB DAQ set and record it with labview. I'm wondering if anyone has any experience in fthis. Are there devices that give an output voltage based on the ambient temp but are powered by thedaq card, or are there ones that are battery powered? Just looking for the cheapest and easiest solution and some ideas and suggestions. Thanks everyone!
