ESP32-based wearable health monitoring MVP for elderly care.
How I got this idea
I noticed elderly health monitoring is fragmented across devices, with no affordable all-in-one solution for continuous tracking.
Problem
- Health data scattered across multiple devices
- No affordable continuous monitoring
- Manual dependency on caretakers for emergencies
Solution
- Built an ESP32-based wearable prototype
- Integrated SpO₂, heart rate, motion/fall detection, and GPS
- Implemented BLE communication for real-time data access
- Focused on MVP reliability over cosmetic polish

Hardest Technical Challenge
Stabilizing noisy sensor data from MAX30102 while managing BLE stack memory usage alongside active sensor polling on a dual-core microcontroller.

What I learned
- ●MVP-first hardware development exposes real constraints early
- ●Sensor accuracy matters more than UI polish
- ●Debugging hardware is very different from software
