The USB sensor came with a mini disk, but my laptop couldn't load this type. But if you google "temper temperature probe software" there is a website where you can download the software for your probe. The software is crude and the worst aspect of the setup. But I got it to output the live digits and expanded the size using " Microsoft magnifier". The data file is a .csv file which I loaded in Excel. One thing to check is the accuracy of the reading against a thermometer you trust. My probe was consistently 3 degree C too cold. You can adjust for this in the software. I like to review the data file to see how accurate my mash profile was. Apparently it can also email you the probe temperature, but I haven't tried this function.
