Pet GPS Collar Tracker Kit
Build a Pet GPS Collar for Estuary Salinity Monitoring Using Arduino Uno
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Combine a pet’s natural curiosity with environmental science by building a collar that tracks salinity spikes as your dog splashes through estuary waters. This advanced kit lets you log TDS (Total Dissolved Solids) readings with GPS coordinates to an SD card, capturing tidal saltwater intrusion data over time. The result is a field-ready instrument that turns a beach walk into a research expedition.
What You'll Build
You'll assemble a rugged, waterproof unit that straps onto a pet collar, reading water conductivity every time your pet enters an intertidal zone. The logged data reveals how far saltwater pushes inland with each tide, visualized later on a map with timestamps. Everything from sensor calibration to data extraction is covered in the AI companion.
What You'll Learn
- Calibrating a TDS/EC sensor for field use and converting voltage to salinity units
- Interfacing GPS, RTC, and SD card modules over I2C and SPI simultaneously
- Writing Arduino code to log geotagged sensor data with microsecond timestamps
- Waterproofing electronics with a custom enclosure for outdoor deployment

Who This Kit Is For
This kit is designed for advanced hobbyists, B.Tech ECE/EEE students working on environmental sensor projects, and researchers exploring tidal estuary dynamics. It fits perfectly into CBSE Class 12 science fair entries, Smart India Hackathon sustainability tracks, and ATL Tinkering Lab guides seeking a deployable field logger.
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 access a custom AI trained on this kit’s circuit, wiring, and code. If you need a human, message us on WhatsApp for quick troubleshooting.
Can I use this kit to monitor freshwater ponds instead of estuaries?
Yes, the TDS sensor works in any water body. The GPS logging maps data spatially, but you may need to adjust the enclosure if the pet stays submerged longer.
Will the collar fit any dog?
The electronics unit measures about 8x6x4 cm and attaches to standard collars with zip ties or Velcro straps (not included). We recommend testing on a dog accustomed to water activity.
How long does the 9V battery last during a field session?
Battery life depends on logging frequency; with the default sketch it lasts 4–6 hours. You can extend runtime by using a larger battery pack or solar panel (not included).
