Ultra-Thin BLE Item Tracking Sticker
Overview
An ultra-thin BLE tracking sticker built around a low-power BLE SoC for proximity detection and item finding, targeting 1.5 months battery life in a compact adhesive-backed form factor.
Features
App-driven 'Find Mode' with real-time proximity updates
Left-behind alerts and 'last seen' location history
Ultra-low-power BLE with aggressive sleep modes
10-15 m line-of-sight range, ~1.5 months battery life
Tech Stack
Deep Dive
Precision Find Experience
Supports an app-driven 'Find Mode' that updates proximity in real time (e.g., far → close → very close), enabling quiet, directional searching without disturbance.
Left-Behind & Last-Seen Support
Triggers alerts when an item exits a safe range and supports 'last seen' history (time and location) to improve real-world recovery workflows.
Ultra-Low-Power BLE Hardware
Designed for periodic BLE advertising with aggressive sleep modes, regulated power delivery, and a thin battery target—aiming for approximately 1.5 months typical operation and 10–15 m line-of-sight range.
Highlights
This project demonstrates a manufacturable, low-cost tracking approach that balances size, battery constraints, and practical everyday usability.
