I need to build a control panel for a freeze-dryer I already own. One aspect of the device will be monitoring the temperatures in the freezing chamber and the condensing chamber. Both of these can reach as low as -50 degrees.
The gadgeteer-compatible temperature/humidity module won’t work for me - it won’t fit. I need something with a separate thermistor that I can jam up into the already-existing housing.
Will the temperature e-block work with the Spider and/or Hydra?
Can I replace the temperature sensor with one that works in my temperature range (-50-40 degrees Celcius)?
What electrical characteristics should I look for when selecting a replacement thermistor? The one I am considering is the Vishay NTCACAPE3C90066 --> http://www.vishay.com/docs/29095/ntcacap.pdf
