You can connect any intrusion detection unit (such as a light fence or a motion sensor) to the input connector J2. Note that an active-low (L) at pin 1 of connector J2 triggers the security system.

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.

The Spark Electron was released a few days ago, giving anyone with the Arduino IDE the ability to send data out over a GSM network. Of course, the Electron is just a GSM module tied to a microcontr… ...
