Ernesto, Dickson and Omega both have simple paper data Logers as well as devices that log temperature and humidity data that down load to your PC. The software makes charts for you or you can dump to Excel and make your own. I have several of the paper chart type and they work well. They even have alarms for high or low warning conditions.
