By certification 
The S7 Optical Dust Sensor product uses Lambert Beer's law to accurately detect the number and concentration of particles in the ventilation ducts of the vacuum cleaner's handle or extension pole duct, sweeping robot, range hood, particle detection instrument and other equipment.
S7optical dust sensor can be widely used in vacuum cleaners, sweeping robots, scrubbers, mite removal devices, clean room environments and other electrical equipment
