Temperature sensor shootout

This lesson is all about temperature sensor shootout, and will show you how to use common temperature sensors and compare results. You will learn how to use DTH22 sensors Dallas 18B20, sensors and 10K NTC Thermistors. See how to wire them, code them, and expected results. A comparison is given as well.

I guess it also depends on your use. An 18B20 would be perfectly adequate to measure the temp in a room since it shouldn't fluctuate that rapidly. I wonder what the stability of readings is over a prolonged duration with the thermistor: would current passage cause heating and higher readings?
It would be interesting to see something on thermocouples.

It's a good question. I recorded a thermistor for several hours and the fluctuations are prevalent. While only a few tenths of a degree. I would expect better. Not sure it it's a thermistor or noise in analogRead. I have to use both however. For simple room temps Dallas are very stable but slow, In my race car telemetry, I need faster reads and can pay the noise penalty. I used thermocouples back in college but not messed with them in years.
