Diseño e implementación de un controlador PID mediante sistemas embebidos para un prototipo de cámara de estabilidad acelerada

Abstract

In the food and pharmaceutical industries, the study to determine the shelf life in their products is something fundamental, so equipment is required to control the variables in a very efficient way. This to have the minimum percentage of error in the results to be obtained and thus, improve the quality and durability in the different places of destination. The present project proposes the development of a prototype of an accelerated stability chamber using a PID control with the objective of testing if the prototype will have a better performance with respect to the stabilization of the temperature and relative humidity generated inside it, compared to an ON/OFF control. The function of this controller is to maintain stable temperature and humidity inside the chamber with the following specifications: temperature at 40 ºC ± 2 ºC and a relative humidity of 75% Hr ± 5% Hr. In addition, for better control and monitoring, all the data generated will be visualized in real time through the ThingSpeak platform, which will display the changes in temperature and relative humidity every 15 seconds.
