What are the cows doing?

A Raspberry Pi weather station written in clojure.

Usage

Cows must be run with sudo to access the devices, so any environmental variables you need must be forwarded using visudo sudo visudo. If you want to use lein, export the LEIN_ROOT environment variable so that lein doesn't get upset when you run it as root.

For logging to xively, export XIVELY_API_KEY with your xively key and pass it on to sudo with sudo visudo

Clone this repository onto your pi.

Create or edit the configuration cows/resources/default-config.edn. Currently a bmp085 for temperature and pressure, a sht21 for temperature and humidity and a ga1a12s202 for light through a mcp3008 a/d converter are available.

Start up the weather station

First run sudo lein deps to download all the dependencies and go get a cup of coffee.

Make sure you are running under tmux or screen, so that you can detach after starting a repl.

apt-get install tmux

tmux

Start up a repl and activate the weather station

Run the following command to start a repl. Go get a cup of coffee because it will take about 5 minutes.

sudo lein with-profile +dev repl

Once the repl is started execute (reset) in the user namespace to start the weather station.
