A leak problem motivated instructables user wpnsmith to make this project to monitor temperature and humidity in order to avoid future problems:
|"Over the past summer, my vacation home had a small water leak for three months, and I realized that had I been measuring the humidity in the effected area, I'd have seen it go to 100% for a long time and I could have dispatched someone to fix the small problem before it became a big one.|
And since I've been playing with Raspberry Pi computers for a while now, and saw an inexpensive temperature/humidity sensor on AdaFruit, I had all the pieces I needed
to implement an inexpensive network-connected monitor.
The Bill Of Materials (BOM):
1) Raspberry Pi Model B
3) SD Card
4) Temperature/Humidity sensor
5 ) Power Supply (I use PoE splitters, but any 5V 1A Micro-USB supply will work)"
