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