Temperature Sensor Types
Thermocouple
Uses the proportionality between temperature and voltage variations
Thermistor
Resistance varies by temperature
Semiconductor-Based
Two identical diodes (effectively) with temperature-sensitive voltage
- vs. current characteristics

Resistance Temperature Detector (RTD)
- Correlates RTD resistance with
temperature
- Film/wire wrapped around a ceramic or
glass core
- PT-100
○ Range: 0.6499K - 1235K ○ 100Ω at 0°C

Room for Improvement
- Hardware improvements
○ Fixing faulty sensors
- Code improvements
○ More autonomy
- Plot improvements
○ File size uniformity
SLIDE 14
Conclusion and Progression
- Dish deformation to be considered in observations
- May suggest ventilation improvements
- Subsequent ideas
○ Adding quantitative analytical processes: averages, deviation, long-term trends, etc.
