The research introduces HERMEDION: A Solar-Powered IoT-Based Vaccine Transport Box with Real-Time Monitoring and Tracking, developed to strengthen cold-chain logistics in underserved areas. Using a Research and Development design guided by the ADDIE model, the prototype was equipped with temperature and humidity sensor, a vibration/shock sensor, an ESP32 microcontroller, SinoTrack GPS, GSM modules, and a Peltier cooling unit. Controlled trials confirmed that HERMEDION consistently maintained vaccines within the WHO-recommended 2–8°C range, with minimal fluctuations across monitoring intervals (ANOVA, p > 0.05). Humidity readings remained stable within 30–60% RH (p = 0.609), and vibration monitoring showed no significant variance across intervals (p = 0.881), validating system consistency. Battery performance tests revealed an average of 14.04 hours without solar support and 19.25 hours with solar integration, a statistically significant improvement (p < 0.001). Sensor responsiveness was rapid, with ESP32 averaging 0.0034 s, KY-002 at 0.0109 s, DHT11 at 1.04 s, and SinoTrack GPS at 22.6 s, ensuring timely data capture and transmission. Usability (WM=4.32), acceptability (WM=4.61), and adaptability (WM=4.46) evaluations all scored “Strongly Agree,” confirming user confidence in functionality, reliability, and ease of use. Overall, HERMEDION proved to be a cost-effective (9,182 pesos), sustainable, and highly adaptable solution for maintaining vaccine stability during transport, particularly in rural, off-grid, and disaster-prone communities in the Philippines.
