Desarrollo de un sistema IoT de monitoreo de temperatura, humedad relativa y estado ON/OFF de un cuarto frío de Inversiones Medina Verbel S.A.S

Abstract

In this project, a monitoring system was implemented to analyze the variables of temperature, ambient humidity and ON/OFF status of the two compressors of the refrigeration system of the fish and shellfish warehouse of the company Inversiones Medina Verbel S.A.S. The design conditions were identified through a survey of information in the field, the monitoring system with IoT architecture was designed using an ESP8266 embedded system which contains a Wi-Fi card to send the information collected from the sensors to the service in the ThingSpeak™ cloud, to be visualized in a prototype mobile app developed with MIT App Inventor. As results, databases were obtained in the ThingSpeak™ cloud of the history, instantaneous measurement and detection of critical limits of ambient temperature and humidity of the cold room in different periods of time since installation, monitoring of the status of the system compressors, refrigeration remotely, have failure notifications by email.
