Monitoreo ambiental con redes de sensores inalámbricos basados en microcontroladores de 32 bits y módulos RF, aplicado a un parqueadero cerrado.

Abstract

In the present degree work, the study and the implementation of a network of wireless sensors for the monitoring of environmental variables (CO2, temperature, air quality) applied in the parking lot of the UCSG is explained, this network is based on microcontrollers of 32 bits (STM32) all this through the development of secondary nodes that will be responsible for sending the information to a main node to be displayed on an LCD. For this system a correlation research of quantitative type was carried out applying the bibliographic and experimental research sources, with this it was possible to get to understand about the WSN its most important characteristics and in this case the communication standards that use the XBee, on the other hand The quantitative research helped to evaluate the data through functional tests of the proposed system that served for the discussion and analysis of the project. As a result of this titration work, a wireless sensor network was implemented, consisting of 3 secondary nodes in charge of the census of the environmental variables mentioned above and 1 main node to which the secondary nodes will be communicated by sending the different types of information through the addresses of the nodes previously established in its data network frame and thus know the levels of environmental contamination that exist in the parking lot of the UCSG.
