Raspberry pi weather station

[Neville Davis]

I have put on the WIKI a link to the work I am doing with this station. It is definitely a work in progress. 

It has all the python scripts in use ( or will be in use) a couple of block diagrams and installation procedures I use.

We are still in the middle of winter so comparison data from my WMR200A and this station has not been compiled yet, but even at only 22 deg centigrade (yes it it freezing :)) I see significant differences at the higher temperatures, so it will be interesting later in the year.

I will be including the driver that has been built and other scripts I am running as soon as I have time.

I used draw.io for the schematics/ block diagrams if anyone is interested..it is online and free and you can download and save to your mac etc.

I still have some cleaning up to do (cabling), some small changes I have made to the main sensor data collecting script to be put on the wiki and the UV index sensor etc but system has been extremely reliable, only down times when I have taken it off line, no restarts, something I cannot say about the wmr200a.

I have attached a couple of photos of the main junction box,Pi3, HDD.

We have had a couple of quite warm days (middle of winter here) and there are significant differences between the outside temperature readings between the 2 systems at the higher temps. The FARS has had a significant effect.

Attached is the xl data of the last 24hrs the red graph is with the FARS and the blue is the WMR200a data. The graph is in degF from the db.

You can see how the WMR200 climbs higher with direct quite warm conditions, and cools a little faster. I have included a screen shot of the graph.
