THERMISTOR(1)

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.
