摘要
文章设计的是PM2.5检测仪,包括AT89C52单片机、攀藤激光传感器、LCD12864液晶显示器和报警器。在本设计中攀藤激光传感器采集空气中PM2.5的浓度值,经过AT89C52单片机处理后,将数据显示在液晶显示器上。系统会将收集到的PM2.5浓度值与用户预先设置的报警值进行实时对比,报警器会在系统检测到超过报警值之后响起,并且会根据污染程度的高低点亮不同颜色的灯给出相应的提示。本设计具有精度高、体积小、续航时间长、便于携带等优点,可直接用于市场推广。
In this paper, the PM2.5 detector is designed, including AT89C52 microcontroller, climbing laser sensor, LCD12864 liquid crystal display and alarm. In this design, the density of PM2.5 in the air is collected by the climbing laser sensor, and thdata are displayed on the LCD after the AT89C52 microcontroller processing. The system compares the collected PM2.5 values in realtime with the pre-set alarm values set by the user, and the alarm will ring after the system detects an alarm value that exceeds thealarm value, and will, based on the level of pollution, light up different colors of the light to give the corresponding tips. The designhas the advantages of high precision, small volume, long life, easiness to carry, and can be directly used in market promotion.
