Description

一种PM2.5检测装置
本申请要求于2016年07月06日提交中国专利局、申请号为201610532185.X、发明名称为“一种PM2.5检测装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及空气质量检测技术领域，尤其涉及一种PM2.5检测装置。
背景技术
PM2.5空气质量检测指专用于测量空气中PM2.5(可入肺颗粒物)数值。适用于公共场所环境、大气环境和室内空气的测定，还可用于空气净化器净化效率的评价分析。
目前的PM2.5空气质量检测方法通常是通过PM2.5传感器进行检测，前述的PM2.5传感器为基于光散射传感器，是根据光的散射原理来开发的，微粒和分子在光的照射下会产生光的散射现象，与此同时，还吸收部分照射光的能量。当一束平行单色光入射到被测颗粒场时，会受到颗粒周围散射和吸收的影响，光强将被衰减。如此一来便可求得入射光通过待测浓度场的相对衰减率。而相对衰减率的大小基本上能线性反应待测场灰尘的相对浓度。光强的大小和经光电转换的电信号强弱成正比，通过测得电信号就可以求得相对衰减率，进而就可以测定待测场里灰尘的浓度。
目前主要的基于光散热传感器的PM2.5传感器包括红外原理粉尘传感器和激光传感器。
红外原理粉尘传感器的结构和电路比较简单。其光源为红外LED光源，气流进出风口主要靠电阻发热以获得热气流流动，有颗粒通过即输出高电平。
激光传感器的结构和电路相对复杂。其光源为激光二极管。采样空气通过风扇或鼓风机推动，通过复杂设计的风道，进行检测。当空气中的细颗粒物进入激光束所在区域时，将使激光发生散射；散射光在空间360°都有辐射，我们在适当位置放置光电探测器，使之只接收散射光，然后经过光电探测器的光电效应产生电流信号，经电路放大及处理后，即可得到细颗粒物浓度值。
然而上述的光散射传感器在潮湿的空气中进行PM2.5检测时，由于空气中的水珠小于2.5微米时，会造成光散射传感器的误判，从而导致了检测精度低的技术问题。
