This study proposes a Web platform, the Web of Things (WoT), whose Internet of Things (IoT) architecture is used to develop the technology behind a new standard Web platform. When a remote sensor passes data to a microcontroller for processing, the protocol is often not known. This study proposes a WoT platform that enables the use of a browser in a mobile device to control a remote hardware device. An optimized code is written using an artificial intelligence-based algorithm in a microcontroller. Digital data convergence technology is adopted to process the packets of different protocols and place them on the Web platform for access by other mobile devices. The platform has high efficiency and cross-platform advantages, with no limitation on the operating system. Message queueing telemetry transport (MQTT) technology is used to simplify the original HTTP protocol. Assume that the mobile device is a subscriber, i.e., the controller, and a microcontroller that connects the sensing device is the publisher. The publishers and subscribers of MQTT need not know each other if they share a message broker. The intermediate agent role is much like a router. Publishers and subscribers do not need to interact, and publishers do not have to wait for subscriber confirmation to cause interactive permission be locked. Nor must publishers and subscribers be online at the same time, and they are free to choose when to get messages. The proposed WoT method is compared with the traditional IoT method regarding data transfer. The results show that the proposed method can save time in processing large amounts of data, as the traditional IoT method wastes time, especially in data format transfer.
