Description: An environmental quality sensor is a device designed to monitor and evaluate various parameters that affect the quality of the environment we live in. These sensors can measure variables such as temperature, humidity, concentrations of pollutants (like CO2, NO2, and PM2.5), UV radiation, and other factors that can influence human health and overall well-being. Integrated into Internet of Things (IoT) systems, these sensors enable real-time data collection, facilitating analysis and informed decision-making regarding environmental management. Their relevance has grown in recent years due to increasing concerns about pollution and climate change, as well as the need to create healthier and more sustainable environments. Environmental quality sensors are key tools in monitoring air quality, controlling pollution, and implementing effective environmental policies. Furthermore, their ability to connect to networks and digital platforms allows users to access critical information from anywhere, promoting greater awareness and action regarding environmental quality.
