Development of IoT Module with Backup and Data-security Functions

Internet of Things (IoT) is one of the most popular research topics. There have been many studies and products about this topic. However, there is few researches about the correctness of data and the mutual support of modules. In this paper, we developed an IoT module with multi-sensor and communication interface. It debugs and confirms the data from multiple modules and sensors using the fusion and the redundant algorithms. It can also sustain or replace a possibly fail IoT module via multiple communication interface. The dynamic security key technology is used to ensure the security of data transmission. Hence the IoT system can be more stable and more secure.
