Desarrollo de un prototipo de comunicación inalámbrica basado en WiFi para transferencia de datos mediante microcontroladores.

Abstract

In today s world, the Internet of Things IoT and automation are highly significant fields, both in everyday life and at the industrial level, where electronic devices of these new generations have wireless communication capabilities that surpass the limitations of traditional wired communication. The objective of this thesis project is to develop a wireless communication prototype that, through WiFi, enables data transfer between ESP32 microcontrollers. The project explores connectivity in various scenarios, ranging from domestic to industrial applications, with a focus on automation. The prototype will allow fast and reliable data transfer between devices. The ESP32 microcontroller was selected for this purpose, as it includes elements for 802.11 bgn WiFi and Bluetooth 4.2 communication. The sensors chosen for data acquisition and transmission include an LDR photoresistor, a Sharp distance sensor, a DTH11 humidity and temperature sensor, and an infrared obstacle sensor. Proteus design software was used to simulate the connections, and the Arduino IDE was utilized for the software programming interface, creating the code for both the master device and the slave devices. In the final stage of the project, the devices were placed in plastic casings to protect the components and to verify their functionality, conducting speed and transfer tests, as well as ensuring the automatic initialization of communication when the devices are powered on. Additionally, speed and protocols were configured to guarantee high performance, providing a viable solution for automation.
