Granted: 2021-10-21
Abstract: The present invention relates to a technology capable of measuring fine dust while being installed outdoors and stably measuring a fine dust level in spite of external environment disturbance (e.g., wind speed change) of an installation site. By refracting a path of reaching wind from the outside to a fine dust sensor member multiple times, the fine dust level is stably and accurately measured in spite of external wind speed change of a corresponding site. Since entering water (e.g., rain and wind) from the outside into a device is difficult, when the device is operated in a state of being exposed to the outside for a long time, durability is maintained for a long time. The present invention introduces an air communication housing block to the inside of the device when external air vertically and upwardly enters, maintains waterproofing well in spite of an unstable environment outside, and smoothly inhales and discharges the air for measuring fine dust.
