基于单片机的室内环境监测仪设计与实现

Design and Implementation of an Indoor Environment Monitor with the SCM

设计了一种以MSP430F449单片机为核心的室内环境监测仪.系统采用模块化设计方法,即每个模块实现特定的功能.分别采用BPW34硅光电池、DS18B20温度传感器和HSI101湿度传感器采集室内光照、温度和湿度,通过编辑软件实现系统的数据采集、处理以及输出显示等.实验结果表明,该环境监测仪工作性能良好,对各项参数的监测精度高,能基本满足对室内环境监测的要求.

An indoor environment monitor is designed based on the MSP430F449 micro-controller as the core. The system is modular in design, that is, each module performs a specific function. Silicon solar cell BPW34, temperature sensors DS18B20 and humidity sensors HSI101 are used to collect indoor light, temperature and humidity in the system. By editing software the data acquisition,processing and output display are achieved. The result shows that the environmental monitoring instrument has the good per- formance, monitoring accuracy of the parameters, and can meet the basic requirements for indoor environ- mental monitoring. And the data results are provided to validate the conclusions drawn.
