I'd like to build a system for monitoring the health of a fish tank. We could build sensors for things like:
  • Temperature
  • PH
  • Nitrates
  • Light Levels (for plant growth)

In addition, we could use the sensor data to automate things like feeding, light control, or even adding water.

Here's a link to some project ideas.

Does anyone have any ideas to contribute? What else could we program it to do?
