I'm starting to work this project (
http://pluggy.is-a-geek.com/arduino/index.html) for my new house.
AVR controller with Linux server, (or DD-WRT direct connection, USB modem compatible).
The CNY70 (which is a reflective sensor, so rather than buying a 4000$ meter, just attach this to the spinning disc u can see in the meter inside, there is a side which is painted in black, so that outputs as (HIGH) ) can be found here in ekt2 (Katranji) very useful for electricity meter, with bang of buck. :D
Home security system,(maybe using the MTC online SMS free service for any alert); *Gas leak*Smoke alert*High drain electricity or water*
Automatic lightning (custom)
Automatic Heat System for each room, using a cheap temperature sensor. (I may use the idea of the ethernet connection, relating to: every room has an ethernet, so no more extra wiring)
I will be using any 40 pins AVR microcontroller.
And the most important thing is, Internet bandwidth monitor l0l...
Any extra info or ideas, i will appreciate this... :)
