León, México includes U-Sound sensors to monitor the noise levels and make smart decisions.
The city of León, located in the province of Guanajuato in México and with more than 1,2 million citizens, has become a Smart City thanks to the deployment of a network of 400 sensors to remotely monitor and manage the most critical parameters identified by the municipal services: air quality, noise, mobility and street lighting. The aim of the project is to create an ecosystem of constant innovation through the efficient use of technology, in order to make decisions based on real data.
The Smart City project includes 20 Urbiotica U-Sound sensors which are continuously monitoring today the noise levels in the hyper center to detect and alert about possible discomfort and incidents due to very loud music, disturbances, signs of distress, among others.

The project deployed by the technology integrator INT (Intelligence and Telecom Technologies) was inaugurated on January 21st, 2020 in the presence of the mayor of León, Héctor López Santillana:
“We want services made and designed according to the needs of our people. This model proposes that citizens are connected in all aspects and all the time in order to make the best decisions and generate the model of development we want for Leon.”
The city of León has thus created a new paradigm of the Internet of Things, to improve the quality of life of its citizens.
