main feature:

working principle

A narrow red laser beam is emitted from the front opening. The detector behind the lens at the other opening is sensitive to incident laser light from a narrow slit overlapping the transmitter beam. If there are fog particles in the overlapping area, the light will be scattered back and be detected by the detector, and an original output signal will be generated. The sensitive area is approximately 30 cm in front of the sensor, and the volume is less than 1 cubic centimeter
