"I first considered using various Arduino or Tessel configurations, but I soon came to the conclusion that the available hardware was not a good fit for my project. I needed weather resistant hardware that could operate in extreme conditions, preferably with low power consumption.
My research eventually lead me to purchase the Davis 6250 Vantage Vue for this project because it had several advantages compared to other solutions I considered."
Hmm. He wanted an off-the-shelf weather station that he connected to a RaspberryPI. Otherwise, Arduino would be a good fit too, especially if one connects various weather sensors to it. It works also in extreme conditions and has real low power consumption.
I built a weather station myself, with an Arduino UNO, connected several sensors (temperature, wind speed, wind direction, rain meter, humanity, light intensity, etc) and wrote a small webserver (ethernet shield) - total hw costs about 120$. The Arduino run without maintenance outdoors (-25° to +45° Celsius) since 2011. I built a web app that runs on a RPi that fetches the data from the Arduino web server with REST API.
- omnibrain 12y agoDo you have a writeup of what sensors you used and how you programmed it? I started to look into this topic but was overwhelmed by the choices. When I finally settled on a path I found out, that the combined wireless sensor devices described are no longer available. Edit: The sensor was called S 300 TH, and it was mentioned in several writeups/tutorials for wireless weather stations with Raspberry Pi.

Good starting point on SF: https://www.sparkfun.com/categories/152 https://www.sparkfun.com/categories/152 Only buy sensors from vendors that provide you an up-to-date Arduino 1.2+ sketch for Uno/Mega or Due! I had to tune my sketch to fit it in Arduino Uno 32k memory (ethernet shield, various sensors code), so if it's your first project maybe use an Arduino Mega (more memory). Test every sketch on its own, then combine all sketches to one sketch. Cables are more reliable than wireless, especially if it should work years without maintenance. You can also use an RPi.

- frik 12y agohaha, I will ask Siri. (iOS auto correction)
