Outdoor Fire Detection System

[mveramo]

I want to build a system that detects an outdoor fire. I imagine such a system could use a heat sensor, infrared sensor or a combination of both. Once the fire is detected, it would trigger the opening of 12 volt water valves attached to my hose bibs, and then feed roof sprinklers.

I can find 12V water valves but no luck in finding an outdoor fire detection system (under a couple thousand dollars). Any ideas on how to build one?

quite hard to create an outdoor fire detector.

I figure it should be a do'able with a heat sensor. If the ambient heat is greater than 140 degrees, then the water valves open.
