Pet GPS Collar Tracker Kit with ESP32
ESP32-C3 Pet GPS Collar Kit – Build a Solar-Powered Tracker That Lasts 6 Months
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Imagine clipping a small device onto your dog’s harness that sends you its GPS coordinates every 15 minutes—without ever needing a battery swap. This kit transforms an ESP32-C3 Super Mini into a solar-charged pet collar that runs outdoors for six months. The waterproof enclosure and BLE link to your phone make it a practical, real-world tracker you can trust during monsoon walks or sunny afternoons.
What You'll Build
A waterproof GPS collar that weighs under 80 grams clips onto any harness. It wakes up every 15 minutes, grabs a fix from the NEO-6M module, and broadcasts latitude and longitude via BLE. The 6V solar panel feeds a TP4056 charging circuit to keep the 18650 cell topped up, so maintenance stops after the first build. The final unit slips into an IP65 enclosure and withstands rain, dust, and curious paws.
What You'll Learn
- Parse NMEA sentences from a GPS module over UART with an ESP32-C3
- Program deep sleep and RTC wakeups to cut current draw to microamps
- Design a solar charging loop using a TP4056, 18650 cell, and bypass capacitors
- Solder SMD components onto a prototype board and assemble a weather-resistant enclosure

Who This Kit Is For
CBSE Class 11–12 students tackling IoT school projects will find every component matched and ready. B.Tech ECE/EEE first-years at NIT, VIT, or BITS can use this as a capstone prototype before diving into a full-fledged animal tracking system. Hobbyists preparing for Smart India Hackathon tracks on livestock monitoring get a complete, solar-powered BLE-GPS node without hunting for individual parts.
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 on the box to launch the AI companion—it knows every pinout and code snippet for this kit. You can also send a photo on WhatsApp and get a response within the hour.
Can I use this on a cat’s collar?
The enclosure is sized for medium and large dog breeds. While a harness might work for a cat, the weight of the battery and panel makes it uncomfortable for most felines. Consider a smaller tag for cats.
Does the kit include a SIM card for remote tracking?
No, by default it uses BLE to relay location to a nearby phone. You can add a GSM module later if you need cellular tracking; the AI companion includes wiring diagrams for that upgrade.
How do I set the 15‑minute interval and solar charging?
The companion app provides pre‑written code that configures the ESP32‑C3 deep sleep timer for exactly 15 minutes. The TP4056 module handles solar input automatically—just connect the panel through the included capacitors and the 18650 cell.
Pet — Ultra compact solar-charged ESP32-C3 BLE tag sends GPS location every 15 minutes. 6-month outdoor life.
