Abstract

Currently, in the teaching process, the combination of blackboard writing and multimedia is often used. When writing with chalk in class, part of the dust generated during the writing process will be inhaled into the lungs through the nasal cavity, causing lung pollution and eventually leading to pharyngitis and rhinitis. In view of the harm caused by dust to the health of teachers and students, this paper proposes a design that uses a sensor to monitor the dust concentration. In the hardware part, the STC89C52 chip is adopted, and the ADC0832 chip is used for analog-to-digital conversion. Finally, the data is displayed on the LCD1602 liquid crystal display. In the software design, the KEIL assembly language is used for programming, and the Proteus simulation software is used for debugging. When the detected dust concentration exceeds a certain threshold, the dust removal equipment will start automatically to reduce the dust concentration in the air. Through testing, the monitoring results of the dust concentration of this scheme meet the design expectations, the test results meet the design requirements, and the scheme has certain value.
