That is a perfect scenario to start with and I have to say that its not that hard to accomplish.

You let the mcModule handle the temperatur calculation and sends to IFTTT when the temperatur is above a value that you have set.
And then you have to decide what kind of message you want to have to your phone, maybe mail or something, that you will configure in your recipe on IFTTT.

Let me know if you want the code for this.
