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:



Step 5: Success!

You did it! You just created your GPS SMS Security Tracking System!

<p>I think you forgot to change timer2 to 0 in your code.</p>
<p>Great project. You make it look so simple. Why not use the cone of safety approach - if the mokick leaves a 10m circle around the bike, then it triggers an alarm. To save power, turn the GPS on/off every x minutes. Just an idea. Love your instructable, just the same. Vielen dank. Mike</p>
<p>Wow! I am deeply impressed. High quality, short but perfect description. Just one suggestion, to avoid false alarm, in case of strong wind, storm etc. So, you will have the first shakes on the parking place. Just imagine a second shake after 30 minutes on the same place because of a strong storm. It would be maybe a good idea to compare the last location with the location before the last one. When both have the same data, it would be a good idea to stop the device sending the message, translating the result as &quot;false alarm&quot;.</p>
<p>really good point for eliminating false alarms.</p>
<p>Don't take this the wrong way. This is not for the poster of this great article.</p><p>For those who would like an off the shelf solution. Get a cheap prepaid or something cell phone with GPS. Install Find Device Manager and you can track it via the web. Add a solar charger and you are set for a while.</p>
<p>This is how I track my kids where abouts. I just sign into their android phones with my google account and shut off all syncing. Then if they dont arrive home when they should I use android Device manager online or my phone and BAM!!</p>
Would it work with the raspberry pi 3?
<p>Would be nice to see a PCB with an GSM/GPS module and an ATMega chip.</p>
That would be great. Can you post a link here for it when done please Kevin?
<p>Very nice! This is what alot of peeps would like for their bicycles<br> too. I'm envisioning something like this, but smaller and hidden in a <br>carbon part. Be it a seat post, handlebar, or a stem. If you had <br>wireless charging, then you really be happening!</p><p>Thanks for your post and I wish you the best.</p>
<p>Great project</p><p>How it is possible to download the schematic without being a &quot;premium&quot; member? </p><p>Also would it be possible to have 12v version? As I plan to use this in a Car.</p>
Well done!
<p>I am in awe.</p>
wow, subscribed :) I always wanted to do a this set up in my car using an arduino mega .. + SMS shield + god module.<br>unfortunately they never worked ;( <br>thanks for sharing ;) <br>
<p>Suggestion: Add some coverage of what happens after the build, e.g. what it takes to activate the sensor and what the received text message looks like. </p>
<p>can sim 808 gsm mdule be use in this project</p>
<p>The issues with email might be because of GMAIL's blocking algorithm to curb spam. Try sending it to another inbox that does not filter messages!</p>
