Abstract: This paper presents the design and development of an automated antibacterial gel dispenser with IoT capabilities for hand disinfection and body temperature monitoring, intended for access control in private spaces. All collected data are stored in a dedicated database. The system was developed using Arduino IDE, XAMPP, Blynk, Autodesk Eagle, Autodesk Fusion 360, and OnShape, integrating sensors such as the MLX90614, FC-51, and AS608. A compact PCB was designed using Autodesk Eagle, while a simple, easy-to-assemble enclosure was modeled with OnShape. A local server was configured using XAMPP to store data in a MySQL database via a PHP script, and the ESP32 microcontroller ensured the overall functionality of the dispenser. The device allows switching between user registration mode, stored data visualization, and standard operation mode, all controlled via the Blynk platform. This system promotes hygiene habits and enables early disease detection. It is currently operational at the Technological Center of Aragón, in the Measurement and Instrumentation Laboratory of the FES Aragón [UNAM].
