== Summary ==
3-point Steinhart-Hart thermistor module for precise temperature measurement.  
Converts analog resistance readings to temperature with optional Fahrenheit units.  

== Description ==
The Thermistor Steinhart-Hart module uses three reference points to calculate temperature based on thermistor resistance.  
It supports an optional fixed resistor for voltage divider configuration, conversion to Fahrenheit, and a choice of whether the thermistor is connected to ground.  
Each point specifies a resistance and corresponding temperature to improve calculation accuracy.
