Decoding the OS V3.0 Sensors (WRM80, WRM100, WRM200 .. etc)
« on: April 12, 2010, 01:59:18 PM »
It took me a few months (most of that was spent learning about RF signals #-o) but I’ve finally cracked the Oregon Scientific V3.0 protocol.

Long story short…. When I first got the WMR100N I wanted to create my own software/website for my station.  That was easy enough since the USB protocol for the base station is well documented on the ‘interwebs’ (http://wmrx00.sourceforge.net).   But then I got tired of reseting the WMR100 basestation every few weeks and that got my ‘nerd’ feathers ruffled. 

I won’t go into the boring details.. but as of today my website is reading the sensors using ~$40 worth of hardware ($30 for an Arduino , $6 for a RF 433.92Mhz RX & $4 for other bits).  Currently I can capture and decode the THGN801 Temp/Humidity sensor, PCR800 Rain Sensor, WGR800 Wind Sensor and the UVN800 UV sensor.

I’ll post the code and details of the protocol to my website this week (needs cleaning) but I’m wondering if anybody else interested in this type of project? 

The possibilities are fun to think about…

How about a ‘box’ that logs the weather data to a SD card.  No computer required.
How about a ‘box’ that logs the weather directly to sites like wunderground.  No computer required.
How about a ‘box’ that plugs into the computer that never needs to be reset (oh wait! I built that)
How about a ‘box’ that logs multiple brands of sensors (OS, LaCosse.. etc)

This is exciting.  My WMR100 is located in a remote location.  A device that eliminates the console reset would be terrific.  I'm definately interested.

Are you still limited to 4 channels or do you have a receiver with more channels?

Oh sweet!  I'm really interested to see how this project turns out.
