Abstract: The safe transportation of temperature-sensitive pharmaceutical products such as vaccines, insulin, and biological medicines is critical to maintaining their efficacy and preventing spoilage. This paper presents the design and implementation of a Smart Medicine Monitoring and Secure Transportation System that ensures environmental control, real-time tracking, and authenticated delivery during transit. A DHT11 sensor continuously monitors temperature and humidity inside the medicine container. When the temperature exceeds a predefined threshold, a Peltier-based thermoelectric cooling module is automatically activated to maintain the required storage conditions. A GPS module provides real-time location tracking, while a GSM module enables remote communication through SMS alerts. The system incorporates two switches to indicate the start and end of the transportation process. Upon reaching the destination, an automated SMS notification is sent to the customer. The electronic lock mechanism is released only after receiving an authorized reply or one-time password (OTP) from the customer, ensuring secure and verified delivery. Additionally, all operational parameters, including temperature, location, trip status, and lock status, are updated to an IoT platform and displayed on an LCD for local monitoring. The proposed system enhances pharmaceutical supply chain reliability, improves security, and ensures compliance with temperature-controlled transportation standards.
