Arduino Temperature Sensor – Winter is Coming

This blog post is old and the code is not up to date. Here’s a tutorial on how to connect the temperature sensor to your arduino. To send sensor data to the internet you need to use a service like COSM.

I’ve started tinkering with Arduino. My first real project was to connect a DS18B20 temperature sensor to Arduino. I have an ethernet shield on the arduino that uploads data to

The temperature sensor is protected by an old film case and is right outside my window. I wanted to have a web site where I can check the outside temperature so I found a small jQuery script that takes JSON data from my Pachube feed and outputs it on a small web site.

Here’s the pachube feed, and here’s the mobile web site. Get the code here.
