Air pollution is a very sensitive issue since currently, Lima is one of the places where there is greater air pollution by particulate matter in the world (PM10). Resulting in long-term health problems, especially in the respiratory and cardiovascular system that is why analyzing and knowing the quality of the air that we breathe, it is essential to prevent health problems in the future. Therefore, this research proposes an air quality measurement system based on Arduino and low-cost sensors that will provide us with a low-cost tool to determine the quality of the air we breathe. This system focuses on a matrix of sensors that will monitor the temperature and humidity conditions, as well as gases harmful to our health and PM10. Finally, these measured values will be reflected in an LCD revealing the values in real time.
