So I have allways been fascinated by smart homes and smart buildings. The main problem with most of the commercial systems is that they are waaay to expensive for a student. So I started looking toward Room automation. And after a few years of doing nothing and doing something
this is the result. RoliHome smart room controler. Equiped with many features built using arduino, processing and Java. It can be constructed for less than a 100EUR and still has some great features. One of the main features is a presence detection. While most systems like this use moton sensors to turn the lights on/off, I use IR door sensors that actually count the number of people inside the room. That way the light wont turn off while you are sitting in front of a computer watching some videos
. You can find more information on my website/blog: http://r00li.com/index.php/rolihome
where you can download thi whole thing and build your own system.
Here are some pictures:
The main system in a box that looks quite nice.
And the presence sensors on the door mounted for testing.
I would realy like some comments and/or questions.
