With the outbreak of the Covid-19 pandemic, vaccination has become mandatory. Further, for effective results, the vaccines should be stored within the recommended temperature range, typically between 2°C to 8°C, transported safely without any mishandling and temperature excursion. In order to assure vaccine potency, it is essential to have detailed information on the entire temperature data recorded at user-defined intervals. In this paper, we develop functionality interaction to bring different sensors, memory, and processing units to an integrated platform, providing a compact, power-efficient, and low-cost commercial TemperatuRE, Humidity, and MOvement Data-logger (THERMOD). Moreover, the THERMOD hardware is packed with interactive algorithms that address the aforementioned concerns and log the real-time temperature and jerks (3-dimensional movement) encountered throughout the journey, and the logged data can be retrieved by plugging THERMOD into the host computer/laptop. The THERMOD hardware formulation and algorithm embedding have been done in the institution lab, which enables end-to-end storage and monitoring. Also, the proposed design is built with the defined standards by health organizations, e.g., WHO. Further, to validate the proficiency of the proposed design, comparative analysis has been done; a) a cost analysis has been done to state the cost efficiency of the proposed solution, b) real-time power performance graphs have been plotted which depict that THERMOD outperforms the existing solutions. Moreover, a number of experiments were performed for the validation of the proposed design.
随着新冠疫情的爆发，疫苗接种已成为强制性要求。此外，为了获得有效结果，疫苗应存储在推荐的温度范围内，通常为2°C至8°C，安全运输，避免任何不当操作和温度波动。为了确保疫苗效力，必须详细了解以用户定义的时间间隔记录的整个温度数据。在本文中，我们开发了功能交互，将不同的传感器、内存和处理单元集成到一个平台上，提供一个紧凑、节能且低成本的商用温度、湿度和运动数据记录器（THERMOD）。此外，THERMOD硬件配备了交互式算法，可解决上述问题，并记录整个运输过程中遇到的实时温度和颠簸（三维运动），通过将THERMOD插入主机/笔记本电脑即可检索记录的数据。THERMOD硬件的设计和算法嵌入在机构实验室中完成，实现了端到端的存储和监控。此外，所提出的设计是按照世界卫生组织等卫生组织规定的标准构建的。此外，为了验证所提出设计的有效性，进行了对比分析：a）进行了成本分析，以说明所提出解决方案的成本效益；b）绘制了实时功率性能图，表明THERMOD优于现有解决方案。此外，还进行了大量实验以验证所提出的设计。
