Analog Temperature Sensor(ST1147)

1．Introduction

A thermistor is a type of resistor whose resistance is dependent on temperature,

more so than in standard resistors. The word is a portmanteau of thermal and resistor.

Thermistors are widely used as inrush current limiter, temperature sensors (NTC type

typically), self-resetting overcurrent protectors, and self-regulating heating elements.

IDUINO for Maker’s life A, B, and C are the Steinhart–Hart coefficients which vary depending on the type and model of thermistor and the temperature range of interest. (The most general form of the applied equation contains a [ln(R)]^2 term, but this is frequently neglected because it is typically much smaller than the other coefficients). Note: For this module, the recommended coefficients of A,B,C are A equals 0.001129148; B equals 0.000234125; C equals 0.
