The invention relates to a particulate matter sensor for detecting particulate matters in air and an automobile air conditioner assembly provided with the particulate matter sensor. The particulate matter sensor comprises: a light source used for emitting light beams; a light splitting assembly which is used for splitting the light beam into at least a first sub-light beam and a second sub-light beam; and a photoreceptor which is used for detecting the first sub-beam and the second sub-beam which irradiate the air. A light beam emitted by the light source can be divided into at least two sub-light beams by the light splitting assembly, and the two sub-light beams can irradiate different positions in the air, so that particulate matters at different positions in the air are detected, and the detection cost is further reduced. The automobile air conditioner assembly comprises the particulate matter sensor, and therefore the automobile air conditioner assembly has the advantage of being low in cost.

    本发明涉及检测空气中颗粒物的颗粒物传感器和装有该颗粒物传感器的汽车空调总成。颗粒物传感器包括光源,光源用于发出光束;颗粒物传感器还包括:分光组件,用于将光束至少分成第一子光束和第二子光束;感光器,用于检测照射空气的第一子光束和第二子光束。光源发出的光束能够被分光组件分成至少两束子光束,两束子光束能够照射空气中的不同位置,从而实现对空气中的不同位置的颗粒物进行检测,进而降低了检测成本。汽车空调总成包括颗粒物传感器,因此也具有成本低的优点。
