Sistema eléctrico de monitoreo de radiación ultravioleta para la prevención de quemaduras solares en la piel de agricultores

Abstract

The objective of this research project was to implement an electrical system for monitoring ultraviolet radiation for the prevention of sunburn on the farmer's skin. The implementation of the system starts from the selection of the electronic components that are going to conform to it, considering the requirements both in technology, hardware and software compatibility that facilitate storage between each one, in this way the sensor was selected as the main elements. ML8511 UV radiation controller to capture the signal, the ESP 32 WROOM 32 microcontroller for data processing, and the ESP 32 TTGO for information display. The designed system consisted of a stage that incorporates an ML8511 UV radiation sensor and an ESP 32 WROOM 32 microcontroller that allows data to be captured, processed, and sent via bluetooth connection using the ESP NOW protocol to the ESP 32 TTGO microcontroller. These data are presented through the led screen included in the ESP 32 TTGO and additionally in the developed mobile application, which shows statistics of the different values that have been sensed throughout the day or week. Finally, the functional tests determined that the implemented system is easy to use for farmers and provides the required alerts for the benefit of the users' health, since prolonged exposure to high levels of UV radiation without adequate protection can lead to a risk to human health.
