温湿度是各种工作环境中最重要的物理量之一。本次设计采用多路温湿度监测系统对被测场所的温湿度信号进行精确测量。该系统以单片机为核心,配合温度和湿度传感器,以及相关的电路组成,实时监测环境的温度和湿度情况。系统中采用温度湿度传感器SHT11,由STC89C52单片机驱动单个通道的温湿度检测,并由MAX232芯片将测量数据发送给中央处理单片机。系统结构电路简单,可广泛使用于距离远,节点分布多的场合。
Temperature and humidity are among the most important physical quantities in a variety of working environments. The design uses multi-channel temperature and humidity monitoring system to measure the temperature and humidity signals at the site for accurate measurement. The system to the microcontroller as the core, with temperature and humidity sensors, and related circuit components, real-time monitoring of environmental temperature and humidity conditions. The system uses temperature and humidity sensor SHT11, by the STC89C52 microcontroller driven single-channel temperature and humidity detection, measurement data sent by the MAX232 chip to the central processing microcontroller. System structure is simple circuit can be widely used in the distance, node distribution and more occasions.
