Ardui’Home, temperature and gas alert for home

Update [17/02] – Project redesigned, look this following post.

Update [2/06] – I’m working on a wireless version

I’ll move in a new apartment very soon, and i have the idea for a new domotic project, ArduiHome, a Arduino Uno, GSM/GPRS Shield, some sensors to measure temperature, humidity, and gas.

The goal of this project is to display, on a LCD, the temperature from four areas.
Sending back temperature and/or humidity value via SMS (no needed at this moment).
Send an alert when town gas or carbon monoxide reach a critical level.
Drive a relay to turn on lighting, or heating system (no needed at this moment). Continuer la lecture de Ardui’Home, temperature and gas alert for home
