Abstract
With the development of society and industry, which brings a lot of convenience to
people's life. However, it will produce a lot of harmful factors in the process of
industrial production, such as coal mining, cement production and other industries in the
dust pollution. In a variety of risk factors on human health effects of the most
serious. The dust harm to human body is the most direct, the most serious is the cause
of pneumoconiosis.When the dust concentration is too high, the high temperature drying
time may explode.
The design used by STC89C52 MCU minimum system, gp2y1010au dust sensor,
ADC0832 ADC module, LCD1602 LCD module, power supply module, buzzer alarm
module and a key module. Single-chip microcomputer real-time through the ADC0832
conversion chip acquisition gp2y1010au dust sensor dust concentration, through the
single-chip microcomputer data conversion processing in the LCD screen display in the
air quality, when the spatial measurement of dust concentration is higher than the set of
dust concentration, buzzer and light-emitting diodes emit sound and light alarm. The
dust concentration alarm value can be set through the buttons.
Key words: GP2Y1010AU0F detection sensors;Dust detection;dust and air quality
