A Review on IOT based Smart Medication Assistance System

This paper presented the Smart Medication Assistance Sys-tem (SMAS), a dual-component solution combining an IoT-enabled circular pill dispenser and a comprehensive Flutter mobile application. The hardware uses a stepper motor-driven six-compartment circular tray with individual medicine parti-tions, a DS3231 RTC for time-accurate autonomous schedul-ing, an audible buzzer for dispensing alerts, and dual-colour LEDs for immediate patient-level dose-confirmation feedback. The mobile application delivers OCR-based expiry scanning with three-tier progressive alerts, configurable alarm schedul- ing, supply-level refill monitoring, and a role-based caregiver access model featuring a compliance history dashboard. SMAS directly addresses the primary root causes of medi-cation non-adherence in an integrated, practical, and afford-able package of hardware components. The system is well-suited for home-based elderly care, paediatric medication man-agement, and community health clinic settings. The offline-resilient EEPROM schedule storage and two-tier LED-plus-FCM feedback loop represent specific advances over the prior art. Future extensions—dual tray, wearable health monitoring, voice output, SMS fallback, and formal clinical validation—will further increase real-world patient impact and deployment reach.
