Pet GPS Collar Tracker Kit with Arduino Nano + LED
Build a Pet SOS Collar Tracker with Arduino Nano – Instant GPS SMS on Single Press
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
One press of a button can bring your lost dog home. This advanced kit lets you build a collar-mounted SOS beacon that anyone who finds your pet can activate – sending you an SMS with live NEO-6M GPS coordinates and a Google Maps link instantly. No app, no subscription – just a rugged, self-contained device you assemble from raw components and customise for your own security and surveillance needs.
What You'll Build
A compact, battery-powered Arduino Nano system sealed inside a velcro wristband that attaches securely to any pet collar. When the large tactile button is pressed, the Nano reads the current latitude and longitude from the NEO-6M module, commands the SIM800L GSM to send an SMS, and flashes two red LEDs to confirm transmission. You'll get the pet's exact location within seconds, even in areas with weak 2G signal, making it a reliable lost-pet recovery tool.
What You'll Learn
- Interfacing the NEO-6M GPS over UART and parsing NMEA sentences to extract lat/long
- Driving the SIM800L modem with AT+ commands and sending SMS in PDU mode
- Building a stable 4.0V power rail from a 3.7V LiPo using an LM2596 buck converter and capacitor filtering
- Soldering a compact prototype on perfboard and integrating all modules inside a wearable wristband

Who This Kit Is For
Ideal for B.Tech ECE/EEE undergraduates tackling embedded systems projects, Smart India Hackathon teams building pet safety prototypes, and advanced makers in IIT/NIT/VIT/BITS labs. CBSE Class 12 students with ATL tinkering experience will also find it a challenging, real-world safety application. If you’re comfortable with soldering and Arduino programming, this kit pushes your integration and power management skills to the next level.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
Scan the QR code to connect with the AI companion that has the full wiring diagram, code, and debugging tips for this project. You can also message us on WhatsApp for direct help from a project engineer.
Does the kit include a SIM card?
No, you need a 2G-capable SIM with an active SMS plan. A prepaid SIM with minimal balance works perfectly; we recommend testing with a known-good SIM before assembly.
How long does the battery last?
In standby the circuit draws under 10 mA, giving over 3 days on the 1000mAh LiPo. The buck converter and decoupling capacitors prevent voltage drops during peak GSM transmission bursts (up to 2A), so the battery remains stable.
Can I modify the code for continuous tracking?
Absolutely. The default firmware sends an SMS only on button press to save power. You can edit the sketch to send periodic location updates, log coordinates to a microSD, or even switch to HTTP-based reporting using the SIM800L’s GPRS.
Pet — Button on wristband sends SOS SMS with live NEO-6M GPS coordinates via SIM800L on single press.
