  • Abstract:
  • Falls among the elderly are a major health concern, often leading to serious injury when assistance is delayed. Commercial alert systems can be expensive and lack customization. This paper presents the design, implementation, and refinement of a low-cost, open-source fall detection system consisting of an ESP32-based wristband and a companion Android application. The wristband uses an MPU6050 accelerometer to detect fall events based on a dual-threshold algorithm (free-fall and impact). Upon detecting a fall, it sends an alert via Bluetooth to a paired smartphone. The Android application, built in Kotlin, receives this alert, provides a window for the user to cancel a false alarm, and if uncancelled, automatically sends an SMS notification to pre-registered emergency contacts. The SMS includes the user's last known GPS coordinates and a Google Maps link to expedite assistance. The iterative development process, including debugging of contact management, SMS delivery, and build environment issues, is also discussed. The resulting prototype demonstrates a functional and affordable solution for enhancing the safety of elderly individuals living independently.
