Tiny GSM alarm system published
After GSM call alarm and GSM SMS alarm as two independent modules, I introduce the Tiny GSM alarm system. The main characteristic of this new version is that this device can operate standalone or as a module for existing alarm system. In previous versions we had only the "enable" pin that armed/disarmed the system. Now, aside from that pin we can arm/disarm the system by calling it with our phone.
