Hello Sven and others interested.Correct me if I am wrong, but does your Velleman data logger not require that a computer is left on all the time? Maximum 4 channels? Good for 2 digital thermometers and 2 digital RH sensors?
The devices I have started building and supplying are stand alone, and can be battery powered. No need for a computer, except when you want to display curves. Just transfer the memory stick that is automatically storing the data over to your computer when you want to see the bulk data. Individual current readings can be seen directly on the display of the monitor/logger, without using a computer.
16 channels, that can be either 16 moisture sensors (direct equivalent straw moisture content in %) or16 combined Relative Humidity and temperature sensors (both temperature and RH from each sensor).
For more detailed specs and price information, see the attached docs. regards Norbert

I live in my Reedbale house for 2 years now and I'm also monitoring Relative humidity and temperature inside the rooms, inside the wall and outside. For the room I have right now digital measuring tool - Velleman datalogger. It gives result like you can see in attachement (indoor). For the wall and outside I just have analog thermometer and hum.measurer :) For me it would be interesting, as to Eddy, to know what is the functionality and price? Thank you Norbert, Sven Aluste Estoniawww.equilibre.ee------------------------------------------------------------------------ ------------------------------------------------------------------------ _______________________________________________ Strawbale mailing list Strawbale@amper....muni.cz http://amper.ped.muni.cz/mailman/listinfo/strawbale
