SMART MEDICINE TRANSPORTATION BOX FOR INJECTABLE MEDICINE

In this paper, we introduced  an IoT-driven smart system designed to monitor and secure the pharmaceutical cold chain. It combines an ESP32 microcontroller with a DHT11 sensor, Peltier active cooling, R307 biometric authentication, and GPS tracking to overcome the shortcomings of traditional passive carriers and bulky refrigerators. Our tests demonstrated that the system quickly regulates temperature (within 180 seconds), provides reliable biometric access control (97% accuracy), and offers smooth, real-time cloud monitoring (1.5-second latency).   As of it’s modular design, the system can be easily scaled, remains cost-effective, and can be used in various scenarios, such as rural vaccination campaigns, disaster relief efforts, and everyday mobile healthcare services. By automatically adjusting to environmental changes and providing robust access control, the system helps maintain the effectiveness of critical medications like insulin and biologics during transportation. We plan to further develop the system by incorporating solar charging for longer use in the field, adding sensors for vibration and light to detect tampering, and creating a mobile app to improve accessibility for healthcare workers in remote locations.
