Hello together,

do you know a way, how i can Set my Temperature Sensor more accurate? I get changes in 1°C steps. Is it possible with an 12-bit ADC to make it more accurate?

Thanks

There is a method named "Correlated Double Sampling" which cancels some measuring errors. Increasing the ADC resolution will result in more precise results at the cost of slower conversions.

Happy coding

Bob

EDIT: Have a look at this AN

Thank you Bob.

Do you know if the Thermistor SHeet would also working with an PT100?.

I didn't find a CDS Sheet for my Psoc 4 just for 3 and 5

There is an RTD Calculator component which is designed for PT100, PT500and PT1000 modules. See datasheet.
