基于zigbee技術(shù)的無線傳感器系統(tǒng)設(shè)計(jì)(文件)
【正文】 rthright convenient, are free to use wireless device, need a large presence in these applications space to decorate a lot of wireless access points, so low prices will play a pivotal role. ZigBee protocol standards as a new wireless connection technique in low cost, low power consumption, work capacity and low speed fields opened a new heaven and earth. ZigBee technology with low power consumption, low cost, short, work capacity to delay and working ability, etc. Currently in abroad, ZigBee work technology has been certain applications. The result of the research of the base ten ZigBee wireless sensor work technology application to have the certain reference value and practical significance for ZigBee wireless technology, and the application fields on the application of the hardware and software to provide the relevant basic platform. Keywords: wireless sensor work, ZigBee 基于 Zigbee 技術(shù)的無線傳感器系統(tǒng)設(shè)計(jì) III 目 錄 摘要 .................................................................................................................................
