Introduction

Calibration of NTC sensors and different

NTC

Note that the temperature of the sensor rises when the current supplies through the resistor. The NTC is nonlinear; see below Calibration.

Negative Temperature Coefficient, NTCLE100E3101JB0 or similar (MF52B NTC Thermistor). The NTC is connected in series with a "shunt" resistor , see Measurement of resistors: voltage divider. Usually is used. The total resistance of the circuit is , which gives


Calibrating: Steinhart-Hart Equation

Steinhart-Hart equation is widely used
