Abstract


Due to the rapid development of some disciplines such as microelectronic machinery system, computer, communication, automatic control and artificial intelligence, it gestates a new network for measure and control that is wireless sensor network since human being enters 21st centuries. The wireless sensor network is a intelligent network system which can carry out data collection, data syncretism and transmission by itself, and the purpose of wireless sensor network is to apperceive, collect and handle the information of objects synergistically which distribute over the region that the network covers. The wireless sensor network technology already becomes a new hot spot for the domestic scientists.This paper gives emphasis to the design of software and hardware of the wireless sensor network node that is applied in collection of temperature and humidity of the earth’s surface, and introduces the main scheme of the wireless sensor network system. This paper designs the wireless sensor network node whose core processor is CC2430 which stands by the IEEE802.15.4 protocol, and introduces the development of the node’s application software which base on the z-stack that stands by the zigbee protocol. The power supply of the wireless sensor network node is very important since the network is placed out of window where almost nobody lives. So the scheme of power supply which uses the sun’s rays and needs Nickel hydrogen battery and Solar battery board is adopted by this scheme. It satisfies the energy demand when the wireless sensor network is placed outside.At present, it is lack of the wireless sensor network system which can be extensively used, so this paper is a significant reference for the application of wireless sensor network about the mearment of the earth’s interface.
