1. Colorado Space Grant Consortium
Thermistors
Why do we need them?
Monitors the temperature of different components in the satellite during orbit, enabling identification of electronics failures.
Monitors the temperatures of the satellite during testing of the to determine accuracy of the model.
What are they?
Non-linear resistors, which change resistance with the temperature

Thermistors
Where are we going to put them?
They will be put on sensitive parts of the satellite, as determined by the thermal model.
How many do we need?
We’ll need about 27

4. Colorado Space Grant Consortium
Thermistors
What will we use?
Probably Getting it from BCcomponents
It’s inexpensive
Between 10K ohm and 100K ohm
High resistance to draw less current
Temperature range of -40 to 125 oC
Fits within required temperature range
Costs between $0.50 and $1.50 each
