Summary

Steinhart-Hart thermistor module for precise temperature measurement. Calculates temperature using Steinhart-Hart coefficients with optional Fahrenheit conversion.

Description

The Thermistor Steinhart-Hart module converts analog resistance readings into temperature using the Steinhart-Hart equation with coefficients A, B, and C. It supports an optional fixed resistor for a voltage divider, conversion to Fahrenheit, and a choice of whether the thermistor is connected to ground. The module can be enabled or disabled as needed.

Properties

• A – Steinhart-Hart coefficient A (default: 0.0011318).
• B – Steinhart-Hart coefficient B (default: 0.0002337).
• C – Steinhart-Hart coefficient C (default: 0.0000001).
• Enabled – Enables or disables the thermistor module.
• Fixed Resistor (Ohms) – Fixed resistor value for the voltage divider (default: 10000 Ω).
• In Fahrenheit – Boolean to convert temperature output to Fahrenheit.
• Thermistor To Ground – Boolean indicating if the thermistor is connected to ground.

Pins

Input Pins

• In (analog) – Analog input from the thermistor voltage divider.

Output Pins
