Make Your Own GPS SMS Security Tracking System

Intro: 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 "[phone]" is not my actual number.

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

https://github.com/adafruit/Adafruit_FONA

https://github.com/rocketscream/Low-Power

STEP 5: Success!

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

Hello ! Where can i find the code for this project. i need it on my communications 1 subject. Thank you

[hyht]

i want to asking that, this project is send SMS again and again, or only one time.???
if again and again then how much time take for next sms???

[24wickhc]

Hi! I was wondering if someone could tell me what type of resistors are used for the circuit? I think there are 2-3 different types but i can’t tell from looking at the picture. Thank you very very much! :)))

[Oluwatunji7]

Please could you tell me what software you used to carry out your circuit simulation because the sim5320 virtually doesnt have component library online that works

[karthikkeyan]

Hi,
Could you please tell me, what kind of antenna did you use for GPS? I couldn't get the latitude and longitude positions. Could you please tell me how did you fix the issue? any inputs will be helpful. Thanks.

[WASANHA]

dear sir
can you help me I am also trying to make a SMS GPS sending circuit for my school.
I have two arduino programs a SMS sending program by pushing a button and the other a GPS showing program on LCD display .
I just cant get the two to work to gether ( send Lat and Lng by pushing a button)
can you plese help me to get the two programd to work together .
But both work seperately.

Ido not have a SIM5320 3G Module
I am using Sim 800 and neo 6m GPS
love to hear from soon.

MY GPS

lcd.begin(16, 2);

lcd.clear();

{
// This sketch displays information every time a new sentence is correctly encoded.
while (ss.available() > 0)
if (gps.encode(ss.read()))
displayInfo();

lcd.print(F("No GPS detected"));

Nice video and work. I am trying to make GPS GSM SMS tracker not for vehicles but family safety or can be used as wearable bands for traking and sending distress signals / SMS? Could you please suggest and share some information around it. Thanks!

[muhda50]

can i use the sim5320A american version at other country

[wolfman4737]

is it possible to change the transducer to a push button so that when you push the button the sim5320 will send a SMS to the user???

[aeroslubis]

I think you forgot to change timer2 to 0 in your code.

[ChiefInstructor]

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

[Knoblauch]

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 "false alarm".

[kamizubi]

really good point for eliminating false alarms.

[RigoC]

Don't take this the wrong way. This is not for the poster of this great article.

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.

[HarleyG8]

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!!

[CarolB149]

Would it work with the raspberry pi 3?

[KevinJ80]

Would be nice to see a PCB with an GSM/GPS module and an ATMega chip.

[JudgieJ]

That would be great. Can you post a link here for it when done please Kevin?

[User1]

Very nice! This is what alot of peeps would like for their bicycles
too. I'm envisioning something like this, but smaller and hidden in a
carbon part. Be it a seat post, handlebar, or a stem. If you had
wireless charging, then you really be happening!

Thanks for your post and I wish you the best.

[smilerhappy.]

Great project

How it is possible to download the schematic without being a "premium" member?

Also would it be possible to have 12v version? As I plan to use this in a Car.
