Concept Board, Send SMS when power shuts down | Telit Cinterion IoT Developer Community

October 17, 2017 - 10:24am, 4834 views


I would like to create an application, that sends an SMS to inform the user that the power supply on which the concept board is attached too, has shut down. My initial thought was to connect a condenser that can read the current in the A/D converter, and when that value reaches zero, it starts the "send SMS" application. However, i have not been able to find the pins for the A/D(by this i mean the Vbatt+ and Vbatt-). Have i simply missed them in the schematics or are they not available, and if not, is there another way to construct this application?  

Thankfull for any help, Willie
