Does anyone have any recommendations on -80C and LN2 tank low-temp freezer alarms that will text or call a cell phone when the temp drops?

I am looking to find an alarm that I can add to existing freezers and LN2 tanks that will call or text me if the temp drops or the unit fails. Thanks!

If you have got any temperature probe you could connect it to any microcontroller system with cellular board. The simplest way I would offer is

1) any temperature sensor

2) complete microcontroller board (Arduino fits perfect)

3) Arduino GSM shield

4) basic programming skills.

Please, believe me, its very simple, it will take no more than some hours even without training. You can make "stand-alone" system as well as integrated in your setup (via LabView, Simulink, etc).
