I'm interested in monitoring the temperature of my oven. 600 degrees Fahrenheit would be sufficient.
1. Use a thermocouple like shown here: Microcontroller-based Temperature ... - Google Book Search
Challenges: Need a cold junction compensator and an amplifier.
Cost: $15 for a Type-K thermocouple + $15 for an AD595 (sourced from sparkfun.com)
2. Use a Thermistor.
Challenges:
Need to find an insulator for the wires to the thermistor that can withstand the oven temperature.
Need to find a thermistor rated for 600 F
Cost: $3 for the thermistor + ??? for the wire insulation.
Any suggestions or alternatives?
