Viewing the data

A project log for re-purposing acurite temperature sensors

Two people have reverse engineered most of the protocol. These things are cheap, and do something I wanted to build. Time to finish the job.

While I was waiting for an Ubuntu install (to do that SDR work), I figured it would be worth some time to author a quick plug-in for Saleae Logic to decode Acurite temperature/humidity sensor data directly.

The decoder I wrote isn't good at returning a byte-at-a-time, which lead me to do an all-or-nothing decoding here. I'm not sure if I'll leave it that way or not, but here it is, decoding two over-the-air received streams and one from-the-transmitter stream between them:

The code is somewhat raw, but it's up on GitHub.
