Cooler of cattle vaccines

Abstract

This paper describes the design and implementation of a cattle vaccine prototype cooler (ENVAG), which aims to monitor the cold chain, which is to ensure that vaccines are properly conserved within temperature ranges established, so that they maintain their original properties, guaranteeing a useful product capable of protecting against vaccine-preventable diseases, from the manufacturer to the end user. The cooler consists of a data acquisition card, a temperature sensor, a refrigerant component, Peltier cell, and the computer. The system measures the temperature inside the cooler through the sensor and the Arduino card, this in turn sends the data to the computer to be processed in the NetBeans software, which is responsible for generating the data sheet to make the graph with the history of the corresponding cooling curve during the process of storage and transport of the vaccines. As a result of evaluating the prototype take 9830 samples in a period of approximately 42 min, time in which the cooler reaches the temperature between 2 ° C and 8 ° C.
