Nowadays cities must include the optimization of services and infrastructures in their management to guarantee their sustainability. In this context, the control of air quality, water, noise and other environmental aspects are essential indicators to guarantee the protection of the health and well-being of citizens. ENVIRA IoT has developed a platform to monitor air quality and integrate it into Smart City platforms. These systems measure pollution in real time, thus collecting valuable information that, integrated with data from other measurements, such as traffic or the circulation of public transport vehicles, helps city authorities to take actions to improve the urban ecosystem. ENVIRA IoT engineers have extensive experience in environmental analysis services, providing customers with specific and reliable information for decision making.
