Description (last modified by valentt) (diff)

The goal is to find out the most energy efficient and weather resistant components to be used in a weather station and to construct one. Ideally it will be a standalone product, although it can be integrated with existing network equipment.

The project could be split into smaller research projects by sensor subsections, which can be standalone modifications to existing network equipment, for example #766.

Basic stations may include

  • thermometer
  • barometer
  • anemometer
  • hygrometer
  • wind anemometer
  • wind vanes

More sophisticated stations may also measure UV index, leaf wetness, soil moisture and temperature, and water temperature.

Most expensive sensor of all is wind speed, because quality wind anemometer is usually around 50$ :(

Also there are quite strict placing regulations for weather stations, because wrong placement could give really bad and inaccurate measurements. Here is more info:

Also when placing temperature sensor in direct sunlight it needs to be placet into a radiation shield, here is a nice example of DIY version: http://www.ruralgeek.com/wpblog/?page_id=70

Here is an awesome link how to build wind anemometer:

Buying wind anemometer is usually most expensive part, around 50€ so why now build our own with 3D printers!

Sparkfun has really nice Weather Meters kit for 70$ which includes:

  • Wind Vane
  • Cup Anemometer
  • Tipping Bucket Rain Gauge
  • Two-Part Mounting Mast
  • Rain Gauge Mounting Arm
  • Wind Meter Mounting Bar
  • 2 x Mounting Clamps
  • 4 x Zip Ties

The cheapest weather station that you can get and that is easily connectable to OpenWrt based routers is Technoline WS 2350. I have found it in Croatia for 860kn (115€).

Only additional thing needed is sunlight shield because stock one is not good enough. FYI guys from Crometeo are selling Stevens shield for 500kn (65€).

Interesting extremely low power arduino based weather station.

I decided to 3D print Stevenson temperature screen, and started collecting few items on Thingiverse which other people already designed.
