摘要
随着科技的不断发展,人们对空气质量的重视程度越来越大,空气质量检测与报警系统是智能家居控制的重要组成部分。本文选取STC89C52作为控制芯片,利用GP2Y1014AU粉尘传感器和SGP30气体传感器采集空气中PM2.5、二氧化碳CO2和挥发性有机化合物VOC的含量,通过ADC0832模数转换后显示在LCD液晶显示屏上,超过阈值蜂鸣器报警。本设计具有实现简单、成本低廉的优点,有一定的实用意义。
With the continuous development of science and technology,people pay more and more attention to air quality.Air quality detection and alarm system is an important part of smart home control.In this paper,STC89C52 is selected as the control chip.The gp2y1014au dust sensor and sgp30 gas sensor are used to collect the contents of PM2.5,CO2 and VOC in the air.After ADC0832 analog-todigital conversion,it is displayed on the LCD,and the buzzer will give an alarm when it exceeds the threshold value.This design has the advantages of simple implementation and low cost,and has certain practical significance.
