I added some new 1-Wire sensors to my weather station this weekend – a barometer and a humidity/temperature sensors from HobbyBoards.  The white square box in the photo is the barometer.  Because it requires more power than is provided on the 1-Wire bus a power injector (unit to the right w/ the red lights) is needed.  The power for the power injector comes from the battery bank which is charged by two solor panels (15 watts each) on the garage roof.  Since a few of these devices use 12 volts DC I plan to calculate the power requirements and see how many I can run off solar power.

Also in the picture is the 1-Wire hub (HA7Net) to the right and to the left is the lightning detector (seen with the 9 volt batter dangling from it)  The coax cable goes outside to the lightning detector antenna which is about 20′ up the pole.

The humidity/temperature sensor was installed in the radiation shield and mounted on the corner of the shed.  I know, this is not a most scientific placement, but I do not have any other place to put it where it has access to wiring.  In this case, I scammed a few cable pairs from the sprinkler control cabling that runs behind the shed.

I edited the /etc/thermd.conf file to include both these sensors and they are now showing up on the thermd graphs as well as being sent to Wunderground.com.
