For those that do not feel brave enough to build a weather station from scratch you can buy a 'Watson W-8681' Weather Station and hook up a Raspberry Pi to it to collect all the data.

Jim Easterbrook (ex-BBC engineer) has a really good write up on the process, and also shares his python code:

I don't know Jim, but I have done the same following his instructions.

This is more useful. The mechanics of the IoT is one problem that might need to be solved, but sourcing good sensors is more interesting to read about.

I unfortunately do not have a good site for a weather station, so I just use the NYS Mesonet: http://www.nysmesonet.org/

(They charge $450,000 a year for commercial customers but still don't have a TLS certificate. The weather stations are good, though.)

Those sensors look very similar to this:
