Design technology for WirelessSsensor node inSSGreenhouse MonitoringSsystemSbased onSInternet of things

Design of the facilities greenhouse monitoring equipment of low cost, low power consumption and easy to expand. In-depth study of wireless network structure, so as to optimize network structure, to reduce the difficulty of network and improve the network efficiency. Choosing MSP430F149 as the core processor; the CC2530 realize the wireless transmission; provide a variety of protocol interfaces, the choice and index parameters of sensor for soil moisture/temperature, air moisture/temperature and illuminance were listed; In addition, set up a wireless sensor network (WSN) for the MESH type structure, designed by the node as a fully functional devices at the same time act as routing of the WSN nodes. After testing, through the network structure and hardware design , the system has simple structure, network advantages of fast and high reliability of data transmission, that can better satisfy the application of wireless sensor nodes in greenhouse monitoring facilities.
