Garduino is an Arduino-based garden monitoring system. Monitor temperature, light level and humidity of a greenhouse/garden and display the readings via a publicly accessible website.
####Garduino (Arduino):
Garduino is a simple sketch that senses temperature, light, and humidity.
It uses the Arduino's Ethernet library to serve a CSV file over HTTP.
Requires Arduino w/ Ethernet Shield, Arduino Time and Ethernet libraries installed.
Sends data in format of:
unsigned large int time_since_arduino_boot, float light (range: 0-100), float temp, float soil moisture (range: 0-100)
####Greenhouse Application (C++ Daemon): Greenhouse is a C++ application runs an infinite loop, regularly reading data from an Arduino via HTTP, recording data to a SQLite DB, and updating a CSV file for the web app to read. Requires g++, cURL and SQLite3.
####Web Application (HTML and d3.js): Lives on same server as Greehouse App and displays data from CSV file in visual form w/ d3.js; requires web server to host files Currently this is just a webpage that displays a d3.js graph of temperature.
##Usage:
Arduino:
Connect your Arduino to an Ethernet Shield and plug it into your router.
Attach a light sensor to pin A0 and a temperature sensor to pin A3.
Upload the "arduino/garduino.ino" sketch to the Arduino.
Let it run.

Server: I used Debian Squeeze with Apache, but the server and OS is really up to you. Curl, sqlite3, g++ required.
sudo apt-get install build-essential apache2 libsqlite3-dev libcurl3-gnutls-dev
cd /var/www
sudo git clone https://github.com/ashleyrevlett/garduino.git
cd server/application/database
cp greenhouse3.db.sample greenhouse3.db
cd ..
sudo make
sudo ./greenhouse ARDUINO_URL (ex.: ./greenhouse http://192.168.1.191)
Create a virtual host that points to the server/public_html directory of the Garduino. On Apache, you can use the included sample file as a starting point. Replace "myGarduino.com" your domain name:
sudo cp server/conf/vhost.com.sample /etc/apache2/sites-available/myGarduino.com
vi /etc/apache2/sites-available/myGarduino.com
sudo a2ensite myGarduino.com
sudo /etc/init.d/apache2 reload
To make the web app accessible outside your local network, you'll need to get a static IP address (or virtual static IP, like from dyndns.org) and configure your router to forward port 80 traffic to the IP address of the server we set up above.
- add data archive view to web app
- add alert/email notification functionality (ex., plant is thirsty, temp too high, etc.).
- adding ability for Arduino to turning lights and irrigation on and off based on readings.
