linux sw for reading & displaying oregon sensors

Post by **docbee** » Sat Jul 07, 2007 2:42 pm

during the last weeks i adapted my linux sw (written in plain c) that reads weather data from the oregon wmr928 to directly read sensor data via the rfxcom receiver. The advantage of this approach is, that you can now use as many sensors as you like (actually, i limited it to 10 of each type) and you dont really need the wmr928 master display.

i will make some further tests on the sw before releasing it under gpl. when things work as expected a first version will be available on sunday night.

feel free to have a look at the results so far in the weather section of my homepage: http://www.pasternak.net/joomla/content/view/40/79/

regards, boris

I'am using xpl-perl for this, which also works like a charm, and also has support for the rest of the supported features of rfxcom.

Look great your page! I came to the same conclusion a while back I don't need the panel anymore. Still need the panel of my Davis vantage pro weather station, is a little harder to adapt the protocol.

the software did record 24h of sensor data without hick up, so i think i can release it for download. building weather graphs also works ok, so here we go...

I have a two new sensors connected to my rig.

1. THN132N
This sensor sends data like the THWR288 with two differences:
- packet length is 44 hex (sample 44ea4c203f8824808414)
- bit #3 of byte #6 indicated negative temperature sign (I assume this is the same with the THWR 288)

2. THGN122N
This sensor acts exactly like the THGR228. (sample 501a2d400f800840153db4)

May be you like to add this to your documentation.

The Oregon RF format document has been updated and the full document is available on the download page now.
The RFreceiver program has also been updated to support the THN132N.
