GuardianEdge

Offline-first AI child safety monitor with zone-based hazard detection

About This Project

GuardianEdge is a Raspberry Pi–ready computer vision system that uses YOLOv8 to detect children near user-drawn danger zones (pools, stairs, windows) in real time, triggering local alarms and SMS alerts even when Wi‑Fi fails.

Problem Statement

Parents of young children cannot watch every moment, and a toddler can reach a backyard pool, open staircase, or unlocked window in seconds. Existing baby monitors only show video after the fact, require constant cloud connectivity, or lack the intelligence to distinguish a child wandering toward danger from normal play. When Wi‑Fi drops during a storm, these systems go silent at the worst possible time, leaving caregivers blind to emerging threats.

Proposed Solution

GuardianEdge addresses the pressing need for real-time child safety monitoring by combining advanced machine learning techniques with local hardware functionality. Its ability to detect children near hazardous areas and provide immediate alerts, even without internet access, empowers caregivers to respond promptly to potential threats, effectively bridging the gap between digital monitoring and physical safety.

What You'll Learn
  • Implement multi-backend YOLO inference with PyTorch, ONNX, TFLite, and Coral EdgeTPU
  • Design zone-based proximity detection using polygon geometry and depth-scaled thresholds
  • Build a state machine with temporal hysteresis to filter transient false positives
  • Integrate GPIO hardware control (buzzer/LED) with graceful simulation fallback for development
  • Implement GSM modem communication via AT commands for offline SMS alerting

Industry-Ready Preparation

This isn't just a project — it's a simulation of how software actually gets built inside a company. You'll see how real teams gather a client's requirements, negotiate trade-offs, and ship in sprints instead of all at once, while picking up the daily rhythm of an engineer's (and tester's) week along the way.

Working With Clients
Requirement gathering, scope negotiation, and expectation management — the way client-facing teams actually handle it.
A Day In The Life
Stand-ups, code reviews, bug triage, and release day — the real rhythm of an engineer's (and tester's) week.
Agile, In Practice
Sprints, backlogs, and retrospectives — see how requirements evolve iteration over iteration, not just in theory.
How Companies Ship Software
From scoping to staffing to shipping — the full lifecycle behind a project like this one, end to end.
Real-world deployment context
A family with a backyard pool uses GuardianEdge on a Raspberry Pi mounted near the patio door: the parent draws a polygon around the pool edge in the dashboard, and the system immediately sounds a local siren plus sends an SMS to both parents' phones whenever their three-year-old crosses the invisible boundary, even if the home internet is down.
