基于单片机空气质量检测系统

Air quality detection system based on single chip microcomputer

由粉尘传感器测量空气粉尘浓度,转换成数字量送单片机,单片机分析处理转换成浓度值再与设定浓度值比较;显示器显示空气中粉尘测量浓度和设定浓度;当粉尘浓度超限时,声光报警;

by dust sensor to measure the air dust concentration, converted into digital quantity to the SCM, SCM analysis into concentration value and value is compared with the set concentration; display of dust in the air of measuring concentration and the set concentration; when dust concentration exceeds the limit, sound and light alarm;
