基于STC的多路温湿度监测系统

Multi-channel Temperature and Humidity Onitoring System Based on STC

温湿度是各种工作环境中最重要的物理量之一。该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 one of the most important physical quantities at all sorts of work places ,which can be accurately measured through the multi-channel temperature and humidity monitoring system in this design. Based on micro-controller, the monitoring system has combined the temperature and humidity sensors with the related circuit to receive and monitor the warehouse temperature and humidity signals. To complete the temperature and humidity acquisition and detection in singlechannel, the system adopted SHT11 sensor and STC89C52 microcontroller driven. Then the measuring data were sent to central processing microcontroller by the use of chip MAX232. In summary, the entire system simplify the circuit and can be widely used in distance and multi-node distributing occasions.
