Ordinary ventilation fans are controlled by a switch; turning on the switch starts the fan to circulate indoor air. With the rise of smart homes, many smart ventilation fans have appeared on the market, using sensors to obtain air quality information so that the fan can "decide for itself" whether it needs to operate.

For example, ventilation fans with added dust laser sensors can be used in bathrooms or other narrow spaces. When someone smokes indoors, the sensor detects smoke particles in the air; when the concentration reaches a set standard, it automatically starts running. Alternatively, ventilation fans with added carbon dioxide sensors can be used in bathrooms, rooms, and kitchens, running automatically if the carbon dioxide content in the air is high. In addition, ventilation fans can be made more intelligent by adding other types of sensors.

Application areas for laser PM2.5 dust sensors: air purifiers, air conditioners with purification functions, PM2.5 detectors, range hoods, smoke alarms, fresh air systems, dedicated PM2.5 sensors, air probes, wearable devices, etc.
