In recent years, a rapid development of many different types of hardware, network devices, communication modules become high value for IoT (Internet of Things). IoT are widely used in many different areas, and in this paper, we developed IoT for maintenance and management system. This system combines a wireless sensor network, heterogeneous network and cloud services with an original management system in order to improve the quality of maintenance and management. Thus, the system scalability and effectiveness was improved. The sensed-data transfer to the cloud database via TCP/IP. Finally, the cloud service platform views the maintenance and management message through webbased interface.
