PM2.5传感器工作原理图

PM2.5传感器的工作原理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粉尘颗粒物的相对浓度。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粉尘颗粒物的浓度。

炜盛科技激光粉尘传感器ZH07

ZH07是一个通用型、小型化激光粉尘传感器模组,能够对空气中存在的粉尘颗粒物进行检测。通过专业算法和标定检测工艺处理,该传感器具有良好的一致性、稳定性。传感器同时具备串口输出和PWM 输出能力,方便使用,体积小,便于集成应用。

ZH07激光粉尘传感器主要应用于空气质量监测仪器、空气净化器、新风系统、便携式仪表、空调、消费类电子产品等设备的配套。
