一种基于I~2C总线的远程测温系统接口技术

【摘要】 介绍了一种基于I2C总线的测温系统接口技术,并根据相应总线规范设计出传感器与单片机的接口。弥补了多数I2C总线测温系统无法进行远程检测的不足,而且与常规的多点温度测量系统相比,接口电路大为简化,可扩展性更强。更多还原

【Abstract】 In this paper,a kind of interface technology for temperature measurement system based on I2C bus is introduced,and an interface circuit for temperature sensor and single-chip microcomputer with I2C-bus criterion is designed.This interface breaks through the limit of long distance measure that most of I2C temperature measurement systems have,and the interface circuit is simpler and could be extended more easily than those of common multi-channel measurement systems.更多还原
