An IoT-enabled smart medicine cabinet built with ESP8266 and a React Native mobile application, designed to help users maintain medication adherence and proper medicine storage conditions.
SmartMediBox addresses the critical challenge of medication adherence by providing an automated, connected medicine cabinet with a companion mobile application. The system ensures patients take the right medication at the right time, monitors storage conditions, and provides real-time updates through Firebase.
- Automated Medication Reminders - Audio and visual alerts when it's time to take medicine
- Smart Compartment System - Automatic opening of the correct medicine compartment at scheduled times
- Environmental Monitoring - Temperature and humidity monitoring with active humidity control
- Mobile Application - Remote monitoring and control via React Native app
- Real-time Synchronization - Firebase integration for real-time data and notifications
- Medication History - Track and analyze medication adherence patterns
