MAX31856 program alerts


I am new to Arduino and am working with 3 MAX31856's to monitor temperature. I would like the program to notify me if the temperature deviates from a ~10 degree C range. Does anyone have any experience with this? Not sure where to start.

What kind of notifications? Flash a light? Send an SMS message?

SMS message would work.

So then you need a GSM shield and a SIM card with an active account.

Make sure to check out the library support for any shield you want to buy before you buy it. If you can't understand the library then don't buy it.

what about for a flashing light?

That could be as simple as an LED with a resistor, plus a couple of careful digitalWrite() statements. Since most Arduinos already have an LED and resistor on pin 13, you don't even have to do the first part.
