基于单总线技术的实验室温湿度控制系统

The System Based on One—wire for Controlling Temperature and Humidity of Laboratory

研制一种适用于实验室的组网式温湿度测控网络。采用新型传感器和单总线A/D芯片模拟信号转换为数字信号,通过单总线输送给微处理器,整个系统具有电路简单、操作方便、系统稳定等特点,是一种实用的实验室温湿度自动控制系统。

Designing a network to measure and control the temperature and humidity of laboratory, it adopts the new-style sensor and one-wire analog-to-digital chip, which convert the analog signals to digital signals and the digital signal is transmitted to microcomputer by the one-wire MPU. So the system has the characteristics of simple heSS, facility to operate and high stability. It is a applied system to measure and control the temperature and humidity of laboratory.
