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.
