Is this just an indicator or are you looking for a temperature sensing method as well? If it's just an indicator then it's going to depend on what sort of sensor you have.

If you need a sensor and indicator, then you have a lot of questions to answer. How accurate does the measurement need to be? How sensitive? What's the operating environment? Is there a need for data collection? Do you have other sensors already? Cost is also a factor, but look at it after addressing the other questions.

Good luck!
