Build a Temperature, Humidity, and Smoke Alarm System with an Arduino

Keeping track of things like the temperature, humidity, and smoke level in your house is important. If you want to make your own system for doing so, Instructables user ICStation shows off how to use an Arduino to do it.

The system here monitors temperature, humidity, and smoke levels and alerts you if those levels reach a certain point. It's just a buzzer at this point, but it'd be easy enough to add in an internet connection so you could get an alert of text or email. You'll need an Arduino along with a bunch of various sensors to get the project rolling, and once it's all set up you'll have a simple, but cheap system to monitor your home. Head over to Instructables for the full guide.
