Diseño y construcción de un prototipo electrónico IoT aplicable a la medición y registro de parámetros en pruebas de velocidad en el área de atletismo.

Abstract

Athletics holds a prominent place in sport, encompassing various disciplines such as sprinting, where accessible technological devices and tools are required to measure and record times with high precision. In Ecuador, the majority of sports centers use manual stopwatches to measure times in the speed events; although they are accurate, certain factors can affect the recorded times; therefore, the objective of this curricular integration research project was to design and build an IoT electronic prototype applicable for measuring and recording parameters in speed events in the field of athletics, consisting of two nodes, includes a Pro-Infrared Lidar sensor for measuring distance and another luna Lidar microsensor that detects the athlete. Data reception and transmission are carried out through RF antennas. The central node uses an ESP8266 card to transmit information via WiFi to a database, which is then displayed in a mobile application. The range and accuracy tests of the Pro and Luna sensors were conducted using the Student's t-test, with a predefined significance level of 0.05; through the analysis, assigned probabilities of t 0.95 and 0.97 were obtained, respectively. Communication tests confirmed that the signal quality remains problem-free up to 80 meters. In the autonomy tests, the battery can power the prototype for 7 hours, allowing for the completion of twenty training sessions with intervals of 1.45 hours each. These results indicate that the electronic prototype developed meets the established requirements for training processes and proves to be competitive compared to commercial equipment with similar features.
