Medivox: Smart Medicine Box — An IoT-Based Intelligent Medication Adherence and Proximity Alert System

Abstract

Healthcare and medical advancement are progressing rapidly, and it is increasingly challenging for technology to support this pace. This paper presents an IoT-based innovative smart medicine box prototype model, Medivox (Medicine Intake Reminder & Alert). The primary goal of the proposed system is to assist patients and elderly individuals in taking their medications on time, eliminating the possibility of missing doses, and preventing over- or underdosing. The system incorporates a servo motor-driven auto-opening lid that activates at pre-scheduled times, a buzzer alert to notify the user, and IR plus weight sensor-based intake detection to confirm whether the medication was actually consumed. A novel proximity-based forgetting alert mechanism uses Bluetooth RSSI (Received Signal Strength Indicator) distance estimation to determine a personalized threshold distance. When the user moves beyond this calibrated threshold without the medicine box, the companion mobile application instantly sends a push notification. Experimental evaluation demonstrates 95.2% sensor accuracy, 98% proximity detection reliability, and 100% push notification delivery rate, confirming the viability of Medivox as a cost-effective, scalable healthcare IoT solution.
