Abstract
A particle detection apparatus and a detection method used therefor, which can detect dust, pollen and smoke particles at a high sensitivity with a sufficiently simple configuration. A particle detection apparatus has a light source and a detection device for detecting light from the light source, and detects particles floating in the air at a position through which the light passes. The apparatus further has an airflow generation/control device capable of controlling an airflow of the air present in the light passing position so as to keep the airflow constant or nearly zero, and an image sensor is used as a photodetector of the detection device. Predefined particles are identified from image information including a moving speed, a size and a shape of a moving object detected by the image sensor.
