Recommend a temperature probe?

Projects General Guidance
1

I want to use thermistor-type temperature probes with my Arduino UNO to measure various temperatures inside my PC. The probes would need to have approx. 18" leads and preferably have a flat head on the end that could be attached to whatever part I want to measure using some sort of tape.

I already have several of these from a 5.25" bay-insert fan controller that I don't use any longer but I can't find the specs on these thermistors, so I don't know how to use them (i.e., how much voltage to use, etc.)

Can anyone provide a link to where I might buy such thermistors that have specs?

Thanks.

As an alternative to thermisters, consider using DS18B20 digital sensors. They avoid any calibration/accuracy issues associated with analog sensors, don't require a dedicated analog input per sensor and you can connect practically as many as you want to the same one-wire bus. They're also very cheap, and are available in various packages including ones with flat mounting surfaces.

Thanks, Peter. I'll check it out.
