SF order on it's way[shipped!]

Since it's been a while since anyone has posted on this forum, just thought I'd post something.

Finally put my order in thats been in the cart on that fateful freeday. added a couple extra things to it as well since I have a mini project going.

Opted to get the polulu trex motor driver as well since my hbridge attempt has yet to work(though I haven't tried to trouble shoot it for a while) .

Got a couple of 20x2's to see what they are like and since they had some sweet hw access. Grabbed a couple of atmel 2313's since they have built in uarts.  

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?
