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 Likeliness/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 differentiation)
    • Lightning Strike Counter
    • Lightning Strike Distance
  • A Nice Bonus Would be Integration with Wireless Indoor Air Quality Monitors that Monitor:
    • Air Temperature
    • Humidity
    • Air CO2 Concentration and maybe Oxygen (latter is less important)
    • Particulate Matter
    • Optional Hydrocarbon Sensors (Detects Offgassing etc, as long as you are careful about all that shouldn't be too huge of an issue, but a sensor can't hurt, just not desperate for one in my opinion)
  • Seems to be a total cost of ~150-200 USD for a MAXED OUT OTS Model
