Abstract

La présente invention concerne un dispositif de détection de concentration de particules pour détecter une concentration d'une matière particulaire contenue dans l'air à l'extérieur d'un compartiment de véhicule, comprenant : un élément boîtier (21) formant un passage d'air (24) à travers lequel s'écoule l'air à l'extérieur du compartiment de véhicule ; une unité de détection de concentration (51) pour détecter la concentration de la matière particulaire contenue dans l'air à l'extérieur du compartiment de véhicule et s'écoulant à travers le passage d'air ; et un boîtier de capteur (52) recevant l'unité de détection de concentration. Le boîtier de capteur comporte une entrée de capteur (521) pour introduire l'air à l'extérieur du compartiment de véhicule à partir du passage d'air dans le boîtier de capteur, et une sortie de capteur (522) pour permettre à l'air à l'intérieur du boîtier de capteur de s'écouler hors du boîtier de capteur et dans le passage d'air. L'entrée de capteur et la sortie de capteur s'ouvrent chacune vers le passage d'air formé par l'élément boîtier.
