Terrible name for the new project. Took a spare Raspberry Pi I had laying around and a little how-to guide, hooked up a DHT22 AM2302 Temperature and Humidity sensor, and am now getting temperature updates on an internal webpage of the brand new server closet.

I will keep it short as none of this is my original work, and credit to the author at Instructables who I followed for the most part. I did not use PoE, his case, or that model of sensor. I wanted it to be a very inexpensive project.

Parts I used instead:
Raspberry Pi Case
DHT22 AM2302 Sensor
