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.
