How does PEMdata work?
PEMdata is a web site where temperature and humidity data can be stored, graphed, and analyzed in a very convenient way. Users first upload their data to the web site. The site stores the data on the server indefinitely. Once uploaded, users can manipulate their data in a number of ways to generate reports or extract information useful for the preservation of collections or HVAC management. Users can see graphs, overlay up to five datasets on one graph, set limits for Temperature (T) & Relative Humidity (RH), and calculate percentage of time within limits. In additon, they can print, save, or e-mail the graphs and analysis.
