Description (Curation) :
You can see the Live demo, you will miss the sensor data, is cause all the code of the sensor is in an Arduino + Ethernet shield running a web server.
Components Materials List
1. Tp Link Router WDR4300, runing custom firmware Quick Mesh Project
2. Raspberry Pi, runing Apache web server
3. Arduino+Ethernet+GY-21, Input device
4. Final Project, Control Alert light system, Output Device
Input “Realtime values in node 1″
I use the code found in this Tutorial. I add the GY-21 sensor to the setup. This sensor works with the I2C protocol, so the idea is to attach different sensor in the array. Here you can download the code and libraries used.
The web server is setup under Raspbian, I SSH to the raspberry and run this sequence of comands:
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install apache2 -y
sudo apt-get install php5 libapache2-mod-php5 -y
sudo apt-get install netatalk
Netatalk allows me easy acces to the server files, so I can edit all the files as they where in my computer.
