摘要
最近中國很多地方出現(xiàn)了嚴(yán)重的霧霾天氣，影響著人們生活的各個方面，最嚴(yán)重的危害還是對人體健康的危害。霧霾的組成十分復(fù)雜，大小有數(shù)百種顆粒物，這些顆粒物通過人體呼吸，進(jìn)入呼吸道，會引發(fā)氣管炎，哮喘等呼吸道疾病。眾所周知，吸煙的人患肺癌的幾率比普通人高60%，而霧霾里含有的有害顆粒物更多，所以霧霾比吸煙更易致癌。因此，對PM2.5/10的測量顯得越來越重要。
本設(shè)計采用Arduino unoR3 開發(fā)板為控制中心，由PM2.5激光傳感器SDS011測量空氣粉塵濃度，595驅(qū)動八位數(shù)碼管顯示當(dāng)前空氣粉塵濃度。當(dāng)空氣中粉塵濃度達(dá)到所設(shè)定限度啟動蜂鳴器自動報警，且能實(shí)時對應(yīng)顯示相應(yīng)的LED燈，直觀提醒當(dāng)前的污染級別。該系統(tǒng)電路簡單、工作穩(wěn)定、集成度高，調(diào)試方便，測試精度高，具有一定的實(shí)用價值。
Abstract
Recently, severe hazy weathers appeared in many places around China, which caused impact on eve-ry aspect of people’s life. The most dangerous threat lies in the health hazard. The composition of h-aze is very complicated, as it is consisted of hundreds of particulate matters that can be breathed into humans respiratory, which lead to many respiratory diseases such as trachitis and asthma. Howe-ver, smokers have 60% higher chances of contracting lung cancer than ordinary people, and haze also contains many other harmful particulate matters so the haze is more likely to cause cancer tha-n smoking. Therefore, the measurement of PM2.5 is becoming more and more important.
This design uses the unoR3 Arduino development board as the control center, by the PM2.5 laser sensor SDS011 measurement of air dust concentration, 595 drive eight digital tube display the current air dust concentration
When the dust concentration in the air reaches the set limit， the buzzer will start to alarm automat-ically and can display corresponding LED light at real time, visually indicating current pollution le-vel. The system has the advantages of simple circuit, stable operation, high integration, convenient debugging, and high-test accuracy and has important practical value.
