DO NOT use a DHT-11 or DHT-22 sensor. Absolute garbage. Spring for the Bosch sensors.
As far as processing the raw data, I'm more interested right now in deciding if I should average which two of the thermometer or barometer readings I've got, and also deciding what to use as a high/low temp for the day - I've had some data dropouts and server crashes where I missed the noon/1pm high temp.
I did get GOES satellite data with a RTL-SDR once a couple of years ago. The antenna is more important than they'd lead you to believe, as is where the antenna is - you pick up a lot of fuzz up to some degrees above the horizon if you place the antenna in an urban setting.
