Make Your Own GPS SMS Security Tracking System

In this project I will show you how to combine a SIM5320 3G module with an Arduino and a piezoelectric transducer as a shock sensor in order to create a security tracking system that will send you the location of your precious vehicle via SMS when it is moved around without you knowing it. Let's get started!

Step 1: Watch the Video!

The video gives you a decent overview on how to create the security tracking system. In the next steps though, I will present you some additional information.

Step 2: Order Your Components!

Step 3: Build the Circuit!

Here you can find the schematic of the project and pictures of my finished circuit as a reference.

Step 4: Upload the Code!

Here you can find the sketch that you need to upload to your Arduino Pro Mini. Make sure to change the telephone number inside the sketch before the upload. And don't worry "+491521234567" is not my actual number.

Don't forget to also download these libraries and copy them into the library folder of your Arduino software:
