Abstract
En la investigación realizada se hizo un diseño, montaje e implementación de un sistema RFID con la incorporación de un sensor de temperatura corporal infrarrojo. El RFID-522 con una frecuencia base de 13.56mhz, trabajando en conjunto con un sensor de temperatura MLX90614 cuya incorporación beneficia el sistema de cerrojo tradicional, también como agregado se utilizó el programa Arduino IDE (entorno de desarrollo integrado), en el cual se realizó toda la programación necesaria incluyendo las librerías necesarios hasta el punto de vista de las funciones básicas de un sistema RFID, como agregados estéticos se utilizaron dos luces LED, rojo y verde para simular el libre paso de un cerrojo o el cierre de este mismo. Se obtuvieron tres casos, en el primero cuando se pasa la tarjeta de identificación y la reconoce automáticamente toma su temperatura y si cumple el requisito de una temperatura corporal estable, se abre el cerrojo; el segundo caso cuando reconoce la tarjeta pero detecta que tiene una temperatura corporal inestable, automáticamente cierra el cerrojo y no permite el paso a pesar que identifica la tarjeta de identificación y en el tercero y último caso si no reconoce la tarjeta, se saltará el paso de tomar la temperatura y automáticamente cerrara el cerrojo y no permitirá el libre paso. Se diseño este sistema que detecta síntoma de COVID 19, en este caso la fiebre, y se realizaron pruebas de campo en donde se obtuvieron resultados favorables se requiere en la verificación de la temperatura porque es solamente un prototipo, para las pruebas se requirió modificar el valor máximo de la temperatura para simular que detecta fiebre. La temperatura promedio es hasta los 37.2 grados de temperatura normal según (Medline PLUS, s.f.) sí sobrepasa esa temperatura es considerado como fiebre, comparando con otros sistemas del mercado se encontró una diferencia en los costos (20 USD) para solo ser un prototipo, como mayor recomendación y para futuras investigaciones se recomienda ensamblarlo en una carcasa para proteger los elementos, también se recomienda programar un microcontrolador para sustituir el Arduino y con esto disminuirá bastante el costo de fabricación del sistema, y por último se recomienda la incorporación del módulo Wifi para realizar un sistema de base de datos en donde cada dato introducido sea almacenado y se obtenga un mejor control de las personas ingresadas así como un mejor control de personas que presentan síntomas de COVID 19.
In the research carried out, a design, assembly and implementation of an RFID-522 system with a base frequency of 13.56mhz was made, working in conjunction with a MLX90614 temperature sensor whose incorporation benefits the traditional lock system, also as an aggregate the Arduino IDE program, in which all the necessary programming was carried out, including the necessary libraries from the point of view of the basic functions of an RFID system, as aesthetic aggregates, two LED lights, red and green, were used to simulate the free passage of a lock or the closure of this, three cases were obtained, in the first when the identification card is passed and it automatically recognizes it takes its temperature and if it meets the requirement of a stable body temperature, the lock is opened, the second case when it recognizes the card but detects that it has an unstable body temperature, it automatically closes the lock and does not allow access even though it identifies the identification card and in the third and last case if it does not recognize the card, it will skip the step of taking the temperature and automatically close the lock and will not allow free passage. This system was designed to detect symptoms of COVID 19, in this case fever, field tests were carried out where successful tests were obtained, it is required to verify the temperature because it is only a prototype, for the tests it was required to modify the value maximum temperature to simulate that it detects fever, the average temperature is up to 37.5 degrees of normal temperature if it exceeds that temperature it is considered a fever, comparing with other systems on the market a moderate difference in costs was found (20 USD) for only be a prototype, as a major recommendation and for future research it is recommended to assemble it in a casing to protect the elements, it is also recommended to program a microcontroller to replace the Arduino and with this the cost of manufacturing the system will be greatly reduced, and finally the incorporation of the Wi-Fi module to create a database system where each data entered do be stored and a better control of the people admitted is obtained as well as a better control of people who present symptoms of COVID 19.
