IoT: Results of an experimental survey with NodeMCU 12e, TFT Nextion and RTC DS1307

Abstract

-With the increase use of the devices for Internet of Things, this study presents the results obtained in an experimental and applied survey, using the device NodeMCU 12e, Tft Nextion and the RTC DS1307 clock, showing a simple application for adjust and show date and time information. Developed in the period of 2017, focusing mainly on the personal experience, evaluating the main characteristics, when using the different devices. The methodology used to obtain the data was an experimental survey with the devices, using the main tools, create to operate the devices, applying the systematic review on the IEEE Xplore base mainly, considering the personal experience when using these types of equipment on different proposals. After applied the experiments, was proceeded to consolidate, discuss and analyze the results. With the experience obtained, was possible demonstrate the results with these kind of devices and your application. Were identified the facilities when using these kind of devices, with the results was possible to demonstrate a way to use and create new solutions for different proposals when studying or using the Internet of Things.Keywords-component; NodeMCU; IoT; Nextion; DS1307; Display; Automation. I.INTRODUCTION The general objective of this work is to present the results of an experiment to study the application and use of NodeMCU 12e devices together with the Nextion display and the time and date control device called RTC DS1307 (Real Time Clock) These devices are usually used in the creation of solutions for residential automation, industrial, robotics, among others.As a specific objective, an Arduino graphical interface (IDE) [1] should be developed, as well as the creation of a small application using C ++, in conjunction with the Nextion display interface, called Itead Editor [9]. a control for date and time, serving as an example for the development of future projects, usually the date and time control is necessary for the recording and sending of events, or incidents, during a data collection, as for example in devices that They measure temperatures, blood pressure, heart rate, humidity. This work was developed by applying research mainly on the IEEE Xplore database, considering studies presented by articles based on the IEEE Computing Society and the IEEE Internet of Things Journal, among other external sources of research such as the Scielo, Google Scholar, among other magazine bases focused on computing and robotics.The results should be presented in the form of instructions and use of the devices, thus allowing an analysis of the necessary steps and considerations that must be taken before the creation of a more detailed project, since the set of devices depends on the type of project and business to the which should be applied.The devices were selected for their low cost, which can be located in the national and international market, usually these devices are used for projects and studies involving the internet of things, thus allowing the construction of solutions for automat...

“…Nextion is a Human Machine Interface (HMI) solution that combines an onboard processor and touch screen memory with Nextion Editor software for the development of GUI HMI projects [33]. The Tft Nextion device will serve as an interface between the user and the device, enabling visualization of the results on the screen as well as changes to settings via the touch screen, thereby facilitating solution development and communication with the device being used [34]…”
