APPLICATION OF AUGMENTED REALITY FOR VISUALIZATION OF IOT SENSORS.

Internet of Things (IoT) and Augmented Reality (AR) represent two technologies that, when combined, create a potent synergy that enhances user experiences, data visualization, and operational efficiencies. IoT involves connecting devices and sensors to collect and process vast amounts of data, while AR overlays digital information onto the physical world, providing users with a visual interface to interact with digital data. Combining IoT with AR allows users to visualize IoT-generated data in real-time through AR interfaces transforming raw data into intuitive, interactive visualizations, making complex information easily accessible and understandable. This paper presents the development of an electric energy meter using the PZEM-004T sensor. The sensor is connected to an ESP32 microcontroller that collects measurement data: voltage, current, power, energy, and forwards them to an IoT platform. The AR application enables visualization of that data in 3D by directing the smartphone camera at the target image. The primary objective of this project is to enhance the user experience by leveraging augmented reality (AR) to visualize IoT sensor data in a three-dimensional (3D) space. This approach aims to move beyond the conventional two-dimensional (2D) display commonly used in IoT cloud platforms. [ABSTRACT FROM AUTHOR]
