A VISION OF INTERNET OF THINGS IN INDUSTRY 4.0 WITH ESP8266

This article presents a case study with the introduction of ESP8266 module, observing the types and levels of bandwidth and communication challenges with wireless network sensors and the necessary requirements in hostile environments in the industry 4.0 era, switching between QoS levels. The module may suffer when applied in industry 4.0, using a communication type machine-to-machine (M2M) to establish connectivity IoT (Internet of Things). The chosen protocol for sending/receiving routing of messages was the Message Queuing Telemetry Transport (MQTT) to be extremely light weight, simple to implement, and running on an architecture publish/subscribe ideal for this type of environments
