Application
Environmental monitoring:
◉At environmental monitoring sites, such as cities and industrial areas, the best dust level sensors are used. These sensors check the amount of particulate matter in the air. This includes PM10 and PM2.5. These particles greatly affect air quality and human health.
The environmental protection department tracks dust levels over time. This helps them see how much pollution is in the area. They can also assess how industrial emissions, traffic fumes, and construction impact air quality.
◉In indoor spaces such as homes, offices, schools, and hospitals, dust sensors are used. These sensors can find dust, pollen, mold spores, and other particles in the air. In newly renovated houses, dust sensors can check for dust and harmful particles. These include particles from decoration materials, like formaldehyde.
Building field:
◉In construction, tasks like digging and mixing concrete produce a lot of dust. Workers put dust sensors in high places, like the edges of the site and on tower cranes. These sensors help track how much dust is made. Local environmental rules may set different dust limits for construction sites at various times.
