摘　　要：针对I2C总线在控制外围设备方面的优势,提出了将I2C总线应用于无线传感器网络中感知节点传感器接入的方案,分析了I2C总线协议的数据传输流程,设计了基于TinyOS的I2C总线设备驱动程序架构,并实现了以ATmega 1281为微处理器的感知节点中光照传感器ISL29002的驱动程序;该驱动程序可以成功驱动传感器并已用于西北温室群监控系统中,应用表明驱动程序能够长期稳定工作。This paper gives the analysis of the advantage for using I2C in simple peripheral equipment controlling, presents the concept of using I2C for sensor switch--in. Then analyzes the Transmission Modes in the I2C protocol, designs the architecture of the driver for I2C device based on TinyOS and implements this driver for the light sensor ISL29002 on Sensor Node which uses ATmega1281 as MCU, With practical application in Northwest Greenhouse Surveillance and Control System, this driver has been regarded as a stable and reliable one.
