Wireless HVAC Sensors - V3 now available

At last we have it. V3 of my wireless HVAC sensor board has been tested and the hardware is done. There were some tweaks to the board over V2, one to fix a mis-routed trace and several geometric improvements to get it to fit inside an electrical box. And now all is well.

Wireless HVAC Sensors - Part 2

Previously I introduced the idea of a battery operated wireless sensor board for sensing temperature and humidity. The intent is to get information to my Raspberry Pi (or Arduino, or any other microcontroller) so that it can intelligently control the HVAC system in my house. Today I give you an update on the project.

Wireless HVAC Sensors (temperature and humidity)

As I've been working to transition control of my HVAC systems over to my Raspberry Pi there has always been one big hurdle to overcome: how to I get the temperature reading from the room I'm interested in to the Raspberry Pi in the basement?
