Russell has been measuring an array of temperature sensors in and around 
his house since October-ish 2011, primarily Dallas Semiconductor DS18B20 
one-wire sensors (previously talk: 2013-06-06 Hacking on the Beagle Bone 
Black). For years, he's had a few Oregon Scientific wireless temperature 
sensors outside, but no way to log the temperatures for posterity. About 
a year ago, in early December 2018, he discovered a project called 
rtl_433 that uses a software defined radio to receive and decode the 
signals coming from these and similar sensors. so that they can be 
logged. This talk will describe a few of the things that are possible 
with rtl_433 and what Russell does and doesn't do with the data.

About Russell:

Russell has been a Linux user since 1992. He worked for a few decades 
doing data management, programming, and analysis for a small scientific 
consulting firm. Since 2005 he has been deeply involved in the Personal 
Telco Project and trying to bring about telecommunications in the users 
interests, while also hacking on router firmware. For two years, he's 
been involved in an active effort to bring publicly-owned fiber 
infrastructure to the Portland metro area (in furtherance of the 
Personal Telco goal). He has a possibly unnatural love for serial 
consoles and RS-232, but is too smitten to be ashamed. He describes 
himself as self-under-employed. Will work on Linux'y things for money. 
Will work on Science'y/measurement'y things for money, as long as Linux 
is or can be involved somehow. He's very interested in trying to solve 
your telemetry problems with off-the-shelf wifi equipment and some elbow 
grease, if you've got some.


ATTENTION! Thanks to a new security policy, attendees will need to enter 
through the 1900 SW 4th entrance by 8PM, just North of the 1930 SW 4th 
that many of us have been using for years. (Do not use the entrance 
adjacent to Hawaiian Express, formerly Taco Del Mar)
