## **Low-cost air, noise and light pollution measuring station with wireless communication** ## ---------- J. S. Botero-Valencia, C. Barrantes-Toro, D. Marquez-Viloria, Joshua M. Pearce ---------- Environmental pollution is one of the biggest problems in the world, the consequences of human development have brought consequences on our ecosystem, which now only try to mitigate. Different types of pollution have a negative impact on the quality of life of humans and other species. It is necessary to know the level of some of these pollution problems in the near environment, to evaluate the impact of some human activities, and to guarantee habitability conditions. For this reason, in this work, it is proposed and developed a low-cost pollution measurement station for outdoor or indoor use, which measures air pollution (particulate matter and CO2), noise (level and direction), light pollution (power and multispectral), and also relative humidity and ambient temperature. The system stores the data in an SD memory or transmits them in real-time to the internet via WiFi. The purpose is to be used in environmental studies, to deploy monitoring networks, or to ensure the habitability of a living or working space.
