This paper presents a wireless sensor network for environment monitoring in smart cities. The prototype described here was applied in the context of the project Cidades Digitais, a Brazilian program to distribute optical fibersto the cities, at Porto Nacional, Tocantins state, Brazil. In terms of architecture, the system was designed with an ESP 32 DevKit V1; DHT 11 sensor for temperature and humidity; MQ-135 sensor for smoke and toxic gas measurement; infrared fire sensor and the ultraviolet sensor Guva S12SD. The communication with the server implements the RESTful pattern and uses Docker containers to provide scalability, which includes a service to warn registered users about issues, APIs to receive and retrieve the data and a database to store it. The system also counts with a Power BI dashboard to visualize and filter the data collected by the sensor network. Also, it is discussed some performance and efficiency topics surrounding the prototype used.
