Thermistors As Accurate Temperature Sensors
Part 2: Application and Results
By: Darren O'Connor and Kasandra O'Malia, Laboratory for Atmospheric and Space Physics, University of Colorado
In Part 2 of this two-part article we apply our method to a real-world application and show how, by combining estimation methods with thermistor characterization data, we can achieve high accuracy measurements over a wide temperature range using the simple voltage divider circuit we described in Part 1. More>>
