Brief notes on hooking up sensors for temperature, humidity and barometric sensors. These notes are kind of an outline of what I used and went through to get the sensors up an running. There are plenty of other detailed notes out there on the web, this might help fill in some blanks. Plus I figured, I took all these notes down and they might as well be published to do some more good.
Raspberry Pi Pinout
DHT22 / AM2302
I followed this example to get the DHT22 sensor up and running all the way to executing the example code
Raspberry Pi Weather Dashboard
I put all if this together to make a dashboard page for the sensors.
