Question:
After reading the new sensor wiki, I'm reminded of a robot I've been planning, that relies on temperture measurments. Basically I want the robot to act like a photovore, only looking for heat instead of light. Is there a way to sense heat at a distance (6-10 feet)?

I've been looking into
I've been looking into this stuff too.
These are some prebuilt

and this is one that I found for super cheap, though I don't think it'll work as well as I want it to....

ooooo
Just make sure it doesn't
IR photodiodes will do the
IR photodiodes will do the trick!
you get what is called Black body radiation, whereby all things that radiate heat also radiate Infra-red waves. Its the principle of how IR imaging works. Hook an IR photodiode up to an ADC and calibrate it and you'll have a somewhat cheaper sensor than the one linked above!
wiki?
Could you link me to the Sensor Wiki? I'm new here. Thanks!
