Red mallada con dispositivos de bajo consumo para iot

Abstract

With the constant advancement in technology and joint knowledge of human being to assume the purpose of meeting the problems of society in different social or cultural fields, the development of new communication systems to exchange the necessary information is inevitable. The Internet of Things. IoT, is the description of a network of all physical objects to connect through the internet and is important for new wireless technologies that are positioned globally. Currently homes have implemented a Wi-Fi wireless network for the simple fact of not adapting to the control of new systems for the connectivity of devices, so the BLE technology prevails the relationship of devices and people so that the system is not totally autonomous or lose the human essence, also has a practical network and that can work on par with other technology without interrupting any process. For the use of the Bluetooth Low Energy. BLE, protocol it is necessary to expand devices with microcontrollers that are necessary to require processes and offer the Bluetooth service (connect to a mobile device), so the ESP 32 module makes it a favorite for integration into a network and the value it has in the electronic market makes it accessible to easily venture into networks. In addition, that its internal structure takes advantage to adapt with some development frameworks such as, Arduino and Espressif which was selected because it has the necessary elements to build based on the BLE protocol, in other words, it is necessary the management of the ESP 32 module to be in charge of presenting common examples of real life adapting with other peripherals such as taking temperature, the presentation of information to be implemented in a home automation area and it is intended to understand an RGB lighting system, red, green, blue, in two types of ESP 32 models to achieve the control that allows to achieve with the nRF Mesh application. The design offered is adaptable to incorporate new nodes or devices provisioned for long distance structures that turns it into a functional network controlling the RGB lighting system. The project ends with the tests obtained that were helpful to illustrate the capacity of a BLE network in a complex structure, so that the connection that has the ESP WROOM 32 module at less than 20 meters with the mobile is important to know the range of reach and thus in the future design the network of devices that allow connectivity between nodes. In particular the creation of groups that can be accessed through the App nRF Mesh is essential for the management of the elements according to their characteristics and how tidy can be the App nRF Mesh when large numbers of provisioned nodes are added, on the other hand, it was found that the application is not harmful to the user and only requests the basic permissions for proper operation.
