Implementación de un prototipo electrónico inteligente de seguridad biométrico con tecnología IoT para un cicloparqueadero.

Abstract

The present graduate research project was based on implementing a smart electronic prototype of biometric security with IoT technology for a bicycle parking lot, which implied the integration of various electronic and technological components. The prototype includes a data acquisition module controlled by an Arduino Nano that receives the information from the prototype's sensors and a control and processing module managed by a Raspberry Pi 4 and an IoT server. A NoSQL database created in Firebase Real-time Database and a USB camera were used to monitor the bike parking lot in real-time. In addition, a biometric sensor that validates the fingerprint of the registered user to open the electromagnetic lock and activate the security mechanisms was incorporated into the prototype. The prototype includes a registration and reservation system through a mobile application developed in Android Studio, allowing more efficient bicycle parking lot management. Various stability and repeatability tests were carried out to validate the efficiency and performance of the prototype; the results obtained were acceptable in all the tests; two members of the cycling teams confirmed the functionality, reliability, and facility of using the prototype. Based on the results, it is concluded that the electronic biometric security prototype with IoT technology is an innovative and reliable solution for security in the cycling sector, providing a high level of reliability and meeting the established objectives. However, it is recommended to carry out a design analysis focusing on minimizing the structure's volume to save space and material without compromising the efficiency and safety of the prototype.
