I agree that I'm asking a lot out of a humble thermistor. My plan is to
have a two thermistors. One on each end of a fairly long pole mounted like
headlights on a mobile robot. Just move slowly toward the one that has the
warmest temp. I hoped that it could at least find close by light bulbs or
alike.
