Three parts

• client part (run on raspberry gathering unit
• server part (run on the cloud server)
• arduino firmware (run on arduino or other avr mcu)

We have two versions of the server - Node.js + MongoDB based server and PHP + MySQL based server.

• mongodb database (mongod running)
• node package manager (npm)

sudo npm install n -g
sudo n stable
git clone https://github.com/hecko/env_monitoring.git
cd env_monitoring/nodejs_server
npm install
node ./app.js

See directory php_server.

• apply MySQL schema to a MySQL database
• edit config.php

Application installed on Raspberry PI gathering data from Arduino and posting the data to the server.

cd /opt
git clone https://github.com/hecko/env_monitoring.git
