650nm 5mW Red Laser Module for PM2.5 Dust Detection

This red laser module can be used as a sensor for air quality detection. It adopts an imported optical lens, with a bright laser spot. Structural composition: 650nm laser part + lens + lens seat + tower spring + structural metal tube + APC circuit board + lead. The smaller the power, the more accurate the detection. For PM2.5 dust detection, we strongly recommend this 650nm 5mW laser module.
