Can I connect a thermistor directly to the iSmart?

For an accuracy of 0.1 degrees C, it would be best to use PT100 resistance temperature devices if possible. The SMT-4PT expansion module can take 4 RTD inputs, each input has a 3rd wire for cable length compensation, and all the calculations are already implemented in the firmware to convert the resistance into a temperature value – no programming required.
