AN70698 - PSoC® 3 and PSoC 5LP – Temperature Measurement with an RTD

Last Updated: 12/27/2013
Version: *H


To make it easy to calculate temperature from ADC readings, PSoC Creator provides an RTD Component. Four example projects are included to demonstrate operation with both low and high levels of accuracy and resolution.

Introduction

Temperature is one of the most frequently measured environmental variables. Temperature measurement is typically done using one of four sensors: resistance temperature detector (RTD), thermocouple, thermistor, and diode.

The following table indicates the PSoC devices, PSoC Creator versions, compilers, and development kits that will work with this application note project:
