PCMeasure system was ‘Featured product of the month’ by
www.temperatures.com

This graphics were created live with PCMeasure and RRDTool.  They show indoor (red) and outdoor (blue) temperature and humidity (green). With RRDTools, unlike MRTG,it is not a problem to show negative values. RRDTools are free available for Unix and Windows.

RRDTool Database was created with this command:

./rrdtool create messpc.rrd DS:aussentemp:GAUGE:600:U:U DS:innentemp:GAUGE:600:U:U DS:feuchte:GAUGE:600:U:U RRA:AVERAGE:0.5:1:5040 RRA:AVERAGE:0.5:12:9600

To read data from PCMeasure and write to database you can use this script (called by crontab):
