Research and Design of a Wireless Sensing IoT Control System Based on BLE MESH Technology

In the rapid evolution of the Internet of Things, wireless communication technologies are particularly crucial. Among these, Bluetooth Low Energy Mesh technology has garnered attention due to its cost-effectiveness, low energy consumption, and high scalability. Although BLE Mesh applications are widespread, challenges remain in achieving stable communication and control among devices in actual sensor networks. This study aims to bridge this gap by designing a wireless sensor IoT control system based on BLE Mesh technology, addressing issues of connectivity instability and high energy consumption. The methodology includes a systematic design and implementation, utilizing BLE Mesh technology to develop a comprehensive system comprising sensor nodes, gateway devices, and application software. Key findings demonstrate the system's capability to support low-power operation of large-scale devices, enhance data transmission efficiency, and feature self-healing properties. This research confirms the potential of BLE Mesh technology in IoT control systems and offers a novel technological approach for the interconnection of smart devices.
