Currently, the active development of all industries occurs within the framework of the “Industry 4.0” concept. One of the key applications of this concept is the implementation of the Industrial Internet of things (IIoT) and applications that will help to reduce the labor costs and costs of enterprises. Among such applications, undoubtedly, we can highlight Internet of things (IoT) and Augmented Reality (AR). The article discusses the interaction of applications of augmented reality with the Internet of things using the example of visualization of plant data collected by sensors and stored in a cloud service. A laboratory testbed is developed to measure the delay in the delivery of data from the cloud platform to the Augmented Reality application. The mechanism for uploading data to the local cloud is used to optimize the quality parameters. It helps to reduce the delay by introducing a new architecture for implementing IoT/AR applications.
