This paper gives the analysis of the advantage for using I~2C in simple peripheral equipment controlling, presents the concept the I~2C protocol, designs the architecture of the driver for I~2C of using I~2C for sensor switch-in. Then analyzes the Transmission Modes in 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.
