Information
Using the analog value log files it's possible to export the analog values into other applications, like Mrtg. Mrtg is primarily used to map network traffic on multiple routers. But it can be set up to make graphs for basically everything. Mrtg needs to run in a Linux environment.
Example mrtg.conf
For temperature sensor.
