IoT based medicine intake alarm system

Medication adherence is critical for effective healthcare, especially for elderly patients and individuals with chronic conditions. This paper presents the Medicine Intake Alarm, an IoT-based smart system designed to ensure timely medication consumption through embedded automation and real-time monitoring. The system features a programmable tray ejection mechanism, IR-based hand detection, buzzer alerts, and GSM notifications for caregivers, providing multi-layered reminders to enhance compliance. Built using ESP32 microcontrollers, GSM modules, RTC, and sensors, the device synchronizes with a cloud backend for schedule management and offers a user-friendly interface for customization. Developed in Embedded C/C++, the system achieves high accuracy in scheduled dose delivery and caregiver notifications. Future enhancements include AI-powered adherence tracking, multi-compartment tray support, and voice-based alerts. This solution demonstrates significant potential to improve patient independence, reduce missed doses, and enable remote caregiver supervision in real-world healthcare settings.
