Overview

This temperature-sensor linearization firmware provides a software routine for measuring and linearizing most common temperature sensors, including resistance temperature detectors (RTDs), thermocouples, thermistors (NTC, PTC, etc.) and analog temperature sensors.

This software includes an analog-to-digital converter (ADC) hardware abstraction layer to enable communication between an ADC and a microprocessor (MCU), a sensor API to convert and linearize sensor data into a temperature value, and examples that demonstrate how to use the source code to read temperature using a sensor, a precision ADC and an MCU.

Features
  • Complete firmware for temperature-to-digital conversion
  • Supports common temperature-sensor types:
    • RTDs (PT100, PT1000, Ni120, etc.)
    • Thermocouples (type K, J, B, T, etc.)
    • Thermistors (PTC, NTC)
    • Analog temperature sensors
  • Easy to modify for multiple sensors
  • Use with other precision ADCs with minimal design effort
  • Support for Windows®, macOS® and Linux® installers
  • Includes examples for sensing RTD, thermocouple and thermistors using:
    • MSP432P and MSP432E microcontrollers
    • ADS124S08, ADS1220 and ADS1261 ADCs

  • ADC hardware abstraction layer (HAL)
  • Sensor API
  • Temperature-sensor examples
