GPS Tracker for Alzheimer's Patients





Introduction: GPS Tracker for Alzheimer's Patients

First a thank you to my Team members Sean Halloran and Gvozden Suvajlo, they came up with this idea and executed it, this project would not be possible without their ideas and skills.

The GPS tracking device is composed of a micro controller, GPS module, cell module, and batteries
all housed in a 3D printed case. The micro controller is programmed to
communicate with both the cell module and GPS module. When the GPS module is
not within a user-specified boundary, the device will send a text message
alert. We made a device that can track people suffering from Alzheimer’s and Dementia could
greatly benefit the quality of life of both that person suffering and the
caretaker. The wandering of a person suffering from one of these mental
illnesses is stressful on everyone and this type of device could limit this.
Current devices on the market are complicated. A device that uses the essential
components would allow for a more user-friendly device allowing the care-taker
to have ease of mind that their loved one is always accounted for. This device
will be developed utilizing readily available components and housed in 3D
printed casings. Experiments were conducted to examine the durability of the
device and to ensure the device remains secured to the person. Future projects involving this would include
utilizing smaller components to keep the device compact. PLEASE SHARE, PLEASE CHANGE AS YOU'D LIKE!! We would like everyone to have this for their loved ones or any purpose they can think of!!

Step 1: Buy Components

1. Arduino Micro

2. GPS Breakout Board

3. Adafruit FONA board

4. GPS Antenna

5. 9v battery (and 3.7v battery 500mah or greater)

6. Pin Headers

7. Female to Female jumper wires

8. 4 of #6-32 screws 2" length plus 4 nuts, 6 2.5mm by 8mm machine screws 6 2.5mm nuts and 2 2mm screws and 2 2mm nuts

9. 1 tamper proof pin 1/4" barrel diameter

10. you will have to 3d print your own case or put it any case you want!

11. Optional- we added a solar board for charging the 3.7 volt battery and utilizing solar panels if wanted.

Step 2: 3D Print Your Case

Solids works files are attached, feel free to modify and print however you'd like!

Step 3: Install Code to Arduino

We have the code attached upload to your micro

Step 4: Wire the Components

Utilize our wiring diagram, we included a button and LED, this is not necessary but we believe they are nice features.

Step 5: Change Whatever Youd Like!

Edit in anyway you'd like, feel free to share and Let us know what changes you have made to improve upon the design!

2 Questions

I have been looking for the "Arduino Micro" but I have not found it. Is there another name for it?

Can someone explain the code line by line for me?Thank you.

Really great stuff! Thanks a lot for sharing. One question: How is the virtual fence configured?

I have the same question, have you figured it out yet? :)

Does anyone know how to set the boundaries? Where does the "text message alert" go and how do I make it go to a certain device, like my phone?

Very interesting idea. How would this stack up to something like a SPOT personal tracker in regards to service costs? I pay about $120 a year, get tracking, roadside assistance, and emergency medical insurance.

In you schematic, what have you hooked up to Pins 2 (green), 3 (green), and 4 (green) of the Pro Micro? Also what is connected to Pins 5 (purple), and 6 (red), of the same Pro Micro? Both items are connected to Gnd on the Pro Micro. I've been looking around and it looks like the Adafruit Pro Trinket would be a good substitute for the Pro Micro ($9.95 versus $24.33). Comments?

More serious:

Apple has the Find My iPhone feature. Maybe a campaign to convince Apple of the need for the device you describe and add it to Find My Parent.

With a smile, inside a:


Shoe Heel (quite a smart idea)



Nose Ring (about 30 years from now)

RFID tag to trigger alarm at door

Hi LoganP2

Very nice ...Thanks for sharing ..

Was thinking of buying one of them cheap GPS-Trackers from Aliexpress or e-bay - but cant find one that meet all my need - except for the one mentioned below ..

... But guess I have a go at fabricating one !! - It for a completely different application - need a long battery life, Waterproof , 'listen-in' function, Vibrate Alert ... Go-fence . SMS alert ..etc...
Something like the JT600B from Shenzhen

I would like if there was a link to web sites associated with the parts list - given in this INSTRUCTABLES ...

Anybody compiled a complete inventory supplier list ?

Anybody have an idea of how much all the individual components cost ..?
