Abstract: This research aimed to develop the prototype equipment for an information system of environmental monitoring and production factors in an agroforestry area with concepts of wireless sensor network technology controlled by microcontroller. There were 2 parts: 1) the sensor node functions various environmental monitoring such as temperature, humidity, smoke in an agroforestry area of agriculturists, and 2) the gateway station functions data collection from the sensor node via the Internet network stored in the cloud database system. Results from the wireless sensor network is the data of the inputs in the agroforestry area, such as temperature, humidity and CO₂ which displays data on the information system that agriculturists can use information to monitoring the environment for agriculture and support an agriculture system management. Improve production processes to increase productivity and predict future output

Abstract: The application of hybrid yarns and their further processing to textile preforms enforce adapted manufacturing processes. Furthermore, a consolidation of cross-section varying parts requires an adapted mold and core system for a reproducible production process. Similarly, the application of hybrid yarns facilitates low consolidation pressures and thus favors the integration of electronic components in fibre-reinforced thermoplastic parts. In this paper, the analyses of the boundary conditions for a process integration of sensor elements in complex fibre-reinforced spacer structures are presented.

Abstract: Trouble-free operation of large-scale mechanical equipment is of great significance to modern industrial production. The existing wireless sensor network nodes are not suitable for condition monitoring of mechanical equipment due to their low acquisition accuracy. In view of this, this article put forward a wireless sensor network for mechanical condition monitoring, and designed corresponding wireless sensor network nodes. These nodes could achieve high-precision acquisition of analog signals. This article described a wireless sensor network structure for mechanical condition monitoring, hardware design of wireless sensor nodes and software design of the system. The precision of the wireless sensor network nodes we designed was verified by experiment. The experiment result showed that the nodes could effectively acquire analog signal with high precision.

Abstract: Association rule mining is an important data mining method; it is the key link of finding frequent itemsets. The process of association rules mining is roughly into two steps: the first step is to find out from all the concentration of all the frequent itemsets; the second step is to obtain the association rules from frequent itemsets. This paper analyzes the collected information of nodes in wireless sensor network and management. The paper presents application of association rule mining technology in the collection and management of wireless sensor network node.
