Making a fire sensor (question)

With a bit of circuitry can this IR phototransistor replace the following sensor?

I plan to interface it with an Arduino

Temperature Sensor?

Ok,

Right now i am planning to build a autonomous robot that puts out fires. It will go up to a tiny fire (about 4 inches) and then drop a tiny bucket of water (2 1/2 inches wide, like the ones that came with the old version of robosapien) on the fire. The bucket will be put on a platform attached to a servo. when the servo turns the bucket will pour. I am going to do this all with picaxe. I know how to use picaxe, and coding in basic.  Anyways what my real question is, Is there a type of sensor that i could use to find the fire and stop before it? Could I use IR somehow?
