Using an arduino together with a couple of sensors, I've created a weatherstation. This page contains (or should contain) all required info to use and maintain this system.
Overview
This weatherstation is based on an arduino pro mini, which has seven different (mostly analog) sensors connected to it. The arduino talks to a soekris over a RS-232 line, which has been modified on the soekris side to provide +5v over a spare wire to provide the arduino with power. I've inserted an PNP transistor inline with this +5v line which is coupled to a GPIO pin on the soekris, providing remote reset functionality. The soekris runs a C application to read the data from the secondary serial port, aggregate it and distribute the aggregated values to both a file-based datalogger and graphite.
System Diagram
TBD
Source Code
The source for this system consists of two parts. One part that is running on the arduino, and one part that is running on a soekris.

- weatherd (to be run on the soekris) https://github.com/r3boot/weatherd
Graphs
For now, there are some rudimentary graphs available on stats.bitlair.nl. This is subject to refinement and recalibration in the future. Also, the namespaces for these graphs may change. To see these graphs, follow the link below:
