Hi! I am looking for hardware to make a temperature probe.
My project involves measure small variances in the temperature (~0.1 C) of boiling water. For my project, I need a temperature probe that is accurate to 0.1 degrees Celsius between the ranges of 80 and 125 C. If this is not possible (or is too expensive) I should be able to use the same temperature range accurate to 0.5 degrees, but 0.1 is much preferred.
The goal of this project is to study how solutes affect the boiling point, and to boil the solution for a set amount of time. Ideally, the device would first take a user input of the boiling temperature and a second input of the amount of minutes the solution needs to boil for. Then, the temperature probe would detect when the solution hits that temperature (starts to boil) and then begin a countdown timer for the specified number of minutes. Once the specified time has elapsed, it should beep.
Originally I sought to complete this project with an Arduino Uno, however none of the probes that I have found operate within the temperature range needed. In addition, this is a laboratory study, so accuracy is paramount.
So my major questions are:
What parts do I need to complete this project?
Is it possible to complete using Arduino? If so, where can I buy a probe that fits my needs?
