+🚀 Proyecto IoT: Monitoreo Ambiental con MQTT y Flespi
+Nombre: Serna Segura Noel Alberto
+Número de Control: 22210354
+
+🌟 Descripción del Proyecto
+Sistema de monitoreo ambiental que utiliza sensores UV (SI1145) y de dióxido de nitrógeno (MICS-2714) para enviar datos a través de MQTT a Flespi, con versiones para Visual Studio Code y Wokwi.
