Development of a monitored refrigeration system for vaccination and biological samples

ABSTRACT

The global pandemic caused by COVID-19 made the world innovate in several areas, especially in health, having as one of its allies the Internet of Things (IoT). Thus, the efforts to circumvent the challenges that arose because of this pandemic, provided the development of several applications. One of the challenges that arose on this occasion concerns the refrigeration of the vaccines for COVID, which need to be refrigerated over a specific temperature range. This challenge was already faced by other types of vaccines, but with the pandemic, it has become even more prominent. Therefore, this paper will present the development of a Refrigerated Monitoring System for Vaccines and Biological Samples (SRM-V&A) capable of monitoring and controlling the temperature of a cooler box that can be used to transport vaccines, biological samples, rapid tests, and medicines. In addition, the SRM-V&A has its own web management system. The system created is intended for the last phase of transportation to the end users and, during operation tests, met the temperatures established in the standards.
