How I got this idea
Identified a critical gap in India's geriatric care market: fall detection and vitals monitoring devices priced above ā¹10,000 excluded the mass market. Conceptualized a sub-INR 6000 solution targeting 140M+ elderly Indians.
Problem
- Fall detection & vitals monitors priced >ā¹10,000 exclude mass market
- Lack of affordable, continuous monitoring for 140M+ elderly Indians
- False positives in existing low-cost fall detection systems
Solution
- Architected an ESP32 + MPU6050 hardware stack for vitals and motion
- Wrote BLE/Serial firmware and built the companion mobile app & public website
- Validated the business model against 3 direct competitors at JIC Accelerator 7.0
- Designed architecture for future integration with ABDM (National Digital Health Mission)

Hardest Technical Challenge
Solving critical false-positive challenges in fall detection by fine-tuning motion thresholds through iterative user testing, alongside managing BLE stack memory on the ESP32.
