Arduino Based Temp and Humidity Display

The temperature in my office at work varies quite a bit depending on the time of day, season, and the whims of the other people I share the floor with. When I’m sitting at my desk shaking uncontrollably or sweating profusely it would be nice to know if it’s due to the temperature or just work related stress. A simple $5.00 thermometer would suffice, but where’s the fun in that? Making my own thermometer might cost ten times as much, but I might learn something in the process and it would be way cooler than any cheap store bought thing? I’d rather make something myself even if I have to pay a “maker’s premium.”

Arduino Based Temp and Humidity Display

Step 1: BOM

Step 2: Design

The first thing to do is layout the placement of devices on the Perma-Proto board. This was the first time I’ve used Fritzing. Fritzing is an open-source electronics design application available for Windows, Mac OSX, and Linux. I chose to try it out on this project because I knew that Adafruit had a large Fritzing library of parts that included the Perma-Proto board. The software makes the layout of parts and connections on the Perma-Proto a snap. The Fritzing file can be downloaded along with the Arduino sketch from GitHub.
