LASSY-2.0

I like to be in nature to go hiking or trail running. In the most cases I'm alone or with my dog under way. My dog isn't Lassie, so she isn't able to run to the next police station or what ever to explain that I had an accident.
How can I contact someone that I had a bad accident or something that makes it impossible for me to call someone via mobile and explain him where I'm.
Thats why I designed this THING and like to share it with others.

What is the LASSY-2.0 (LifeAssistingSystemSilentYapper) doing?

The acceleration module (MPU6050) is detecting that you move, jump or making flic-flac. If the MPU6050 is detecting no acceleration the arduino sents via bluetooth connection (HC-06) a signal to the installed app on your mobile. The app will sent automatically a SMS with the GPS coordinates to a police station or to the real Lassie.
The energy supply is ensured by a power bank what is connected via USB to the LASSY-2.0, for easy charging and to shut down the LASSY-2.0
