Thermistor
This section describes how to physically connect the sensor and how to configure the
setup in MONITOR.
The sensor used in this example is a PS103J2 thermistor. This sensor is a 10k ohm type
and has two leads, so we need to add our own “completion” resistor (0.1% or better).
This completion resistor will help MONITOR to calculate the resistance of the thermistor
by measuring the voltage generated by two resistances (a known and unknown).
Since our thermistor is a 10k Ohm type, we will use a 10kohm completion resistor. The
equation
10000*X / (VREF-X)
Where the 10000 is our completion resistor in ohms and X
is the voltage reading.
will give us the resistance of the thermistor, which can then be placed into the Steinhart-
Hart equation to calculate temperature. Note in MONITOR, the Steinhart equation
already converts the retuned value from Kelvin to Celsius.
To wire it up, connect like so (NOTE: The lead numbers are not marked with numbers,
this is just a reference.)
