CDW-21A PM2.5 Dust Sensor using laser scattering principle, detecting the existence of dust particle concentration in the air, the minimum can detect 1.0um particles, best dust level detector sensor has a good consistency and stability.According to different usage environment ,there are indoor type and outdoor type to select.
Environmental monitoring:
◉At environmental monitoring sites such as cities, industrial areas and traffic arteries, best dust level detector sensor are used to monitor the concentration of particulate matter in the atmosphere. These include particulate matter (PM10) and fine particulate matter (PM2.5), which have a significant impact on air quality and human health. For example, by monitoring the concentration of dust in the atmosphere over a long period of time, the environmental protection department can understand the pollution situation in the region and assess the extent of the impact of industrial emissions, traffic exhaust, construction and other activities on air quality.
◉In indoor environments such as homes, offices, schools and hospitals, dust sensors are used to detect dust, pollen, mold spores and other particles in the indoor air. For example, in newly renovated houses, dust sensors can help monitor dust and harmful particles released by decoration materials, such as formaldehyde polymer particles.
Building field:
◉In the construction process, such as earthwork excavation, material handling, concrete mixing and other operations will produce a lot of dust. Workers install dust sensors at high places such as the perimeter of the construction site and the tower crane to monitor the emission of construction dust.Depending on local environmental regulations, the concentration of dust at construction sites may have different limits at different times.
