NAME

thermistor − compute temperature indicated by a thermistor

SYNOPSIS

thermistor

DESCRIPTION

This component computes the temperature indicated by a thermistor in a voltage-divider ladder. It uses the Beta-parameter variant of the Steinhart-Hart equation, described here:

PINS

thermistor.N.t0-c

float in Reference temperature of the thermistor, in degrees Celsius (typically 25 C). This must be set before the component can compute the thermistor temperature. The reference temperature information is supplied by the thermistor manufacturer.

thermistor.N.r0

float in Resistance of the thermistor at the reference temperature. This must be set before the component can compute the thermistor temperature. The reference resistance information is supplied by the thermistor manufacturer.

thermistor.N.beta

float in Beta parameter of the thermistor (sometimes just called B). This must be set before the component can compute the thermistor temperature. The Beta parameter is supplied by the thermistor manufacturer.

thermistor.N.r-other

float in Resistance of the other resistor in the voltage-divider ladder. This must be set before the component can compute the thermistor temperature.

thermistor.N.v-total

float in Supply voltage of the voltage-divider ladder.

thermistor.N.v-thermistor

float in Voltage drop across the termistor.

thermistor.N.temperature-c

float out Temperature sensed by the thermistor, in degrees Celsius.

thermistor.N.temperature-k

float out Temperature sensed by the thermistor, in Kelvins.

thermistor.N.temperature-f

float out Temperature sensed by the thermistor, in degrees Fahrenheit.

thermistor.N.resistance

float out Computed resistance of the thermistor.
