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
