Our system addresses the issue of monitoring indoor air and aims to improve its quality, acting on the elimination of harmful elements, impacting common environments and for private use, and presenting the relationship between the quality of outdoor air with the indoor one. It is also creative and innovative because it uses UV-C light technology for the purification process, in addition to the MEMS sensors (with fluorescence spectrometry techniques). The solution is based on scientific studies already developed with favorable results, and is a relevant project, acting as an agent to combat Covid-19. It can be used on land, in companies, shopping malls, and it can also be used in space, as it is adaptable to the place of use.
Our team chose this challenge given the current situation in world and because its problem has persisted for generations. When analyzing the challenge several times we understand the need to develop a solution that monitors the ambient air and purifies it. We saw the outdoor environment affected that indoor air, leading to the decision to use the Meteomatics API and the AWS integration with NASA to inform users when the outdoor environment is contaminated. For the development of the site we use Node.js and React Native; for prototyping 3D models, we use Solidworks. We had difficulties in the ideation process and to develop a project that was innovative and had a global impact. During the development of the project, we saw that another problem was the feasibility of it, and after many researches, we found a solution to the problems encountered, in addition to a system that performed both the monitoring of the internal environment and the air purification, ensuring a good result for the user.
