An Arduino is equipped with a piezo sensor to detect impact, and a GSM shield takes care of the texting. It’s an interesting concept, similar to requiring police officers to wear body cameras.

Arduino has two new boards out which deliver connectivity - the Arduino MKR WAN 1300 (LoRa) and the Arduino MKR GSM 1400.

Arduino devices have had the option of a GSM linkup for awhile, but getting that cellular link to truly strut its stuff hasn't always been easy, even for those of us who'd be inclined to program ...

It wasn’t that long ago that projects with cellular connectivity were everywhere, but with 2G no longer universally available ...

If you've mastered the art of Arduino, but haven't yet been brave enough to toss in a bit of GSM communication, the how-to guides linked below definitely deserve your attention.
