Arduino Weather Station Update

Its been a while since i have posted anything to do with electronicals and as i have been tinkering with the its been taking forever weather station i thought i would post an update.

The major change has been to the power system. I found these rather cool Wemos 18650 boards that take care of charge, voltage boost etc etc for a couple of bucks. The specs are perfect for all sorts of projects and will match up perfectly with the 6V solar panel i have to go with this and will charge at a max of 0.5amps. The cheep lipos have a combine capacity of 3.5amp hours, and the project atm draws about 0.1 amp hours, so good for say 30 hours without sun, which in Brisbane should be more than enough, if not I will buy some real lipos and use them instead, but, once i start dropping the micro into standby, that current draw will drop dramatically.

I have the code all working for the modules installed, humidity, temp, pressure, rain, I still have Lux and UV sensors to install. The code will poll the sensors every 15mins, save the data to SD card and push a copy of the data to my home server where I am still working on a web interface and graphing to display the data. High and Low data for the day is saved at midnight and pushed to the home server also.

And not to be outdone, I have even done some woodwork and 1/2 built a house for this which will then get installed in the garden. Also I have coming from china a rain gauge and depth module for measuring how much rainfall there has been, the rain sensor i have in the above image just detects rain, not how much or how intense it is.
