When whittling down the list of projects for Practical Arduino I never expected the Weather Station Receiver project to be one that gained so much attention. To be honest I was dubious about whether enough people would build it to justify its inclusion, but felt that even if it wasn't built very often it was still worthwhile as an example of how to do signal timing analysis and bitstream decoding. I'm glad we put it in, because it seems to be one of the more popular projects!
Reader Kelsey Jordahl contacted me yesterday with details of a modified version that reads data from a La Crosse TX4U system, using the circuit from Practical Arduino but with modified software to deal with the different data format.
Kelsey's system logs the data and generates nice-looking graphs that are displayed online. For more information (including the modified source code) check out:
Oh yeah, and this is probably a good time to mention that Freetronics is now stocking fully pre-assembled Arduino shields for the Weather Station Receiver project. The very first one was sold and shipped to a reader in Queensland, Australia, yesterday morning.
The shield implements exactly the same circuit as shown in Practical Arduino, but with a dedicated PCB design rather than using a protoshield. There's more info on the 433MHz Receiver Shield for Arduino page at the Freetronics site.
