Hi guys! I want to build a weather station, actually this is a school project, but from all projects I wanted this one (it seems fun). I want my weather station to show me barometric pressure, relative humidity, temperature, wind speed, direction and rain gauge. I worked before on embedded systems, but never on Arduino or Seeeduino. And here is where I need your help. What should I use for my project (for a 200$ budget)? I need to show all those infos on a PC (I need to make an app for that) and I will do it either by wireless connection or wired connection. Also I was thinking about using a solar panel for powering my outdoor sensor and a LiPo battery of 2000mAh. I would also like my WS to be connected wireless to the PC. I don’t know what are the best options and I really need your help guys. 
Lots of DIY weather station projects are described on the web, including many that use Arduinos and wireless communications. Google “diy weather station arduino” for starters.
Thank you for your answer, I did some searches online, but so far none of the results included all the elements I need to show on my PC. I will google more and maybe I will find something that fits my criteria.
Start here and add/delete as desired ?
