Open Source Weather Station

Basics

• A "weather station"
• Essentially a self contained sensor suite
• Is modular, but should measure most/all of these things:
  • Air temperature
  • Relative humidity
  • Vapor pressure
  • Barometric pressure
  • Wind speed
  • Wind Direction
  • Gust/Gust Liklyness/Frequency (Via Software from other wind stuff)
  • Solar Radiation (General Brightness, and/or UV brightness)
  • Day/Night Time/Cycle (Via software from solar stuff)
  • Precipitation (any form, with differentation)
  • Lightning Strike Counter
  • Lightning Strike Distance

Minimum Viable Product

• "Self Contained" ie is one unit, often on a post
• Lots of Networking Options Via Modules (NONE (just storage on sd etc) , Wired XLR, Wired USB , CAN BUS or Ethernet etc
• All sensors are modular
• Can handle any* weather (* being whatever is desired by end user)
• Durable
• DIY (or premade)
• As low cost as possible
• Modular

Basic Design

General Overview/Conceptual Design

• Stacked "modules" similar to Arduino Shields and Rasberry Pi Hats
• Each is sealed (need to determine weatherproof connectors
• Either the modules are "flush" or there is a seperate shell/cover
• Arduino and/or Raspberr Pi as the core computer/microcontoller (unless a custom board is used)
• The main controlls and electronics are in one module
• Cables is in another
• Optional Onboard Storage is on another
• Each wireless thing is a module
• Max "stack" no more than 50cm excluding the pole for mounting, and any antennae etc
