01 · Problem Statement

Addressing Pet Safety

Traditional tracking systems fail to provide instant safety alerts or integrated vitals context. PetGuard Pro resolves these boundaries.

01 / Latency gaps

High Sync Latency

Consumer pet tracking collars typically rely on periodic updates, leaving large windows where pets are unaccounted for. We stream telemetry continuously through Firebase RTDB.

02 / Delayed notifications

Late Escape Awareness

Owners often learn of escapes long after boundary breaches. Our system immediately triggers a piezo collar alarm buzzer to startle pets and halt further escapes.

03 / Inadequate context

No Health Insights

Standard locators offer no vitals indicators. We mount temperature probes (MLX90614) and pulse registers (MAX30102) to track thermal levels and heart rates alongside coordinates.

04 / Stale state dashboards

Undetected Disconnects

If collar units run out of battery or lose signal, applications still show stale values. Our client checks the age of incoming database packets, updating status flags instantly.

⚡ Onboard Dual Connection

Collar automatically synchronizes local telemetry data packet frames using home Wi-Fi or fallbacks onto SIM800L cellular lines when walking outside.

💓 Real-Time Vitals Tracking

Direct registers readings map optical heart rates and IR surface temperatures. Triggers notifications if indicators pass safety limits.

👟 Accelerometer Step Counting

Translates 3-axis MPU6050 accelerometer ticks directly into live step counting goals, monitoring active play metrics on the dashboard.

🚧 Dynamic Virtual Fence

Compares incoming coordinates against boundary circles. Escalates alerts and triggers hardware buzzer alarms if the perimeter is crossed.

📊 Behavior Analytics PDF Reports

Compiles today's path coordinates records, average vitals levels, and step counts into an exportable PDF behavioral summary report.

🎫 Support Tickets Desk

If collar connections drop, status updates to offline. The built-in desk logs tickets in Firestore to handle issues directly.
