My intended purpose was setting up systems with high thermal mass and relatively slow rates of change.
The PID controller I developed to control the fans cooling the optic table in my projectors uses NTC sensors, with a system resolution of 0.03c. Reading temperature is fast, in fact "over-sample" by averaging 20 readings. This reduces noise (which throws the Derivative stage of a PID loop into spasms and drives the engineer tuning the loop nuts). I was going to add streaming output to that design, however the ATtiny13 doesn't have the IO for serial, and it's code space (1k) is full to the undies running a PID loop so I can't even bit bang...
