How much parts / what will I need for my home automation?

by Olavxxx on Wed Mar 10, 2010 10:29 am

Hi there.

Look at my apartment sketchup here:

I want to read humidity and temperature in all rooms:
banned
Bedroom
Bathroom
Hallway
Livingroom x 2 (I want one sensor near floor and one near ceiling).

I want to control (on/off):
1 Electric oven in the bedroom
2 Electric ovens in the livingroom
1 Electric fan to transfer heat from livingroom to bedroom (?)

I have found that the SH1101 features both humidity and temperature sensor.
Is this good for temperature-readouts, or should I use dedicated tempsensors too?

If I can use the SH1101, I guess I need:
6 x SH1101 for sensors

Then is my main question:
What else do I need? Can I do it all with one arduino, maybe the arduino mega?
I could buy some zigbee compliant outlets and use an Xbee on the Arduino?

Wiring the sensors from the rooms to the main arduino should be doable, as long as the sensors support long wires and still give a good readout. I could put the arduino in the hallway. Also I would like to log everything to mysql (thinking I need another Xbee and the USB cable to connect it to a PC).

Scalability (future expanding) is also a factor which I would pay some more for.

I know there is no 1 way to do this, but 1000 ways.. but keep in mind I want to do it not too expensive, but I also want it done properly.. if I have to choose between expensive and crappy, I will just refrain from doing it :-P but some hundred $ I could use max.. like 2-300$.

I only need to control 3 ovens and maybe a fan between livingroom and bedroom.
ps. I am also going to lower the roof to add insulation.

Hope you guys have pointers :-) can I do this with one Arduino mega + 2 * xbee + sensors + some wiring?
Will I need some pullup for the sensors, if I use long wiring? or is it easiest to put some smaller arduinos in the other rooms + xbees, or maybe just run long signal + dedicated power wires?

Sorry for a long and messy post.

Check out this web site: http://www.shed.com/
It will show you how to do this and more. I have been using this for over 15 years. My whole house is automated.

I realize you probably mean "radiator", but I had to chuckle. :)

Have a look at http://tuxgraphics.org/electronics/
I am using their avr/ethernet board for a temperature reading project
