SM-LS-01A is a digital versatile particle concentration sensor based on the principle of laser scattering. The module is equipped with a laser diode (laser) and a photoelectric sensor, which can continuously collect and calculate the number of suspended particles of different particle sizes in the air per unit volume, that is, the particle concentration distribution, which is then converted into mass concentration and output in the form of a universal digital interface . The single-chip computer calculates the concentration and size of the particles. This laser counting sensor can measure PM1, PM2.5, PM1.

​

Small size, light weight, about 49 (length) × 12 (width) x 35 (height) mm, 24g.

It can distinguish small particles of cigarette smoke and large particles of dust.

Lead-free and comply with RoHS standards. It can detect particles as small as 0.3 ㎛.

(Dust size in the household: 20 ㎛, sand storm particle size: 10 ~ 20 ㎛, cigarette particle size: <1 ㎛)
