摘要
介绍了基于Atmel公司的AT89C55WD单片机设计的空气质量检测控制系统。该系统能够对环境空气的温度、湿度、尘埃粒子浓度等进行检测。配合外围功能部分,能实现对上述空气指标的控制。同时,可与上位机进行RS-232串行通讯,并能将环境空气的详细历史资料存储在EEPROM中备查。
The article introduced a kind of ambient air-quality control system that is based on microcontroller chip AT89C55WD.The system can detect the ambient air elements?押the humidity?熏the temperature and the particulate concentration.With its function part?熏the system can change the above-mentioned elements.At the same time?熏it can transmit the detected data into PC by means of RS-232 protocol?熏and can record these historical data into the EEPROM.
