Construction sites are important places for urban construction, and there is a close correlation between their construction activities and dust generation. During processes such as earth excavation, material transportation, and concrete mixing, a large number of particulate matter are released into the air, forming dust. According to relevant studies, each square meter of the construction site can produce dozens of grams or even hundreds of grams of dust per day during the construction phase. This dust not only affects the living environment of the surrounding residents and reduces visibility but also poses a hazard to human health. PM2.5, with a particle size of less than 2.5 micrometers, can directly enter the human lungs and trigger respiratory and cardiovascular diseases. As one of the major sources of air pollution, dust will also aggravate the formation of haze weather, having a negative impact on the urban air quality.

Against this background, the Dust Monitor has emerged as a powerful tool to address the dust problem at construction sites. It is installed on the construction site and, through its built - in professional sensors, can conduct real - time monitoring of the concentration of dust particulate matter in the air. These sensors accurately monitor the data of particulate matter with different particle sizes, such as PM2.5 and PM10, and convert the data into clear and readable values, which are intuitively presented to the construction site management personnel and the environmental protection department.

The Dust Monitor operates around the clock. Once the dust concentration exceeds the standard, it will quickly send out an alarm signal. This provides a crucial basis for timely implementation of dust - suppression measures, such as starting the sprinkler system, increasing the frequency of watering, and adjusting the construction process, thereby effectively preventing the further spread of dust. Moreover, it can simultaneously monitor meteorological parameters such as temperature, humidity, wind speed, and wind direction. The comprehensive analysis of these parameters helps to deeply understand the generation law and diffusion trend of dust, providing comprehensive data support for formulating scientific and reasonable dust - suppression strategies.

From the perspective of practical application effects, the extensive use of the Dust Monitor has greatly enhanced the environmental management level of construction sites. Through the real - time monitoring data, the construction units can accurately control the dust pollution situation and reasonably allocate resources for dust - suppression work. The surrounding residents also benefit substantially, as the air quality has improved and the health problems caused by dust have gradually decreased. Its emergence not only meets the current strict environmental protection requirements but also plays an important role in promoting green construction and facilitating the sustainable development of the city. It plays an irreplaceable role in protecting the ecological environment and ensuring people's healthy lives and is an indispensable part of modern construction site management.
