low voltage temperature sensor in tht package

@Nca78 - good to know, thanks!
@rozpruwacz - having a 4K7 thermistor at the end of a few meters of cable is OK ... unless the cable is an inch away from a power motor, fluorescent light, etc. Does not matter much what type of cable you use if you keep it short (a couple of meters).
Don't use large value thermistors like 1Meg.
Try to use twisted cable to connect the thermistor to Arduino if shielded is not an option, twisted cables can reduce some type of interference and noise.
These things may help you ... hopefully:smile:

as a general rule, take different analog reads and then average them out, this way you can mitigate interference effect on the readings

@rozpruwacz - one more thing you can do is to place a small ceramic capacitor (like 1nF to 10nF ... or just experiment with other values) in parallel to the thermistor, that will also filter noise.
