This article describes the design of a wireless network of sensors for monitoring CO2 in the air and noise levels developed for the urban area of the city of Loja. The design starts with the analysis of the functionality, protocols, and characteristics of the Wireless Sensor Networks (WSN) with the implementation of Zigbee communication technology. For the design of the network, the monitoring scenario was determined through the greater concentration of socio-economic activity within the city, from these scenarios the sectorization of the city center was preceded, establishing the main sources of emission of CO2 and noise levels. Then, the simulation was carried out in the Riverbed Modeler software to determine the evaluation parameters, such as the transmission speed, the delay and the packets received from the chosen technology. Also, the sensor nodes and the coordinating node were designed, which allows the establishment and communication of the network, through the XBee PRO S2B module, of the Zigbee technology. Finally, to evaluate the designed network, two types of tests were performed: a reception power level test and a validation test of the operation of the network, based on the construction and implementation of prototypes of the proposed sensors, a node coordinator and two sensor nodes (one node for CO2 monitoring and one for noise). The generated information is displayed in a graphical interface developed in the VS Express 2017 software.
