OFweek Supplies A Wide Range of Laser Dust Sensors
Laser dust sensor is an efficient and accurate air quality monitoring tool. It uses the principle of laser scattering to measure the concentration of suspended particles in the air.
It is widely used in environmental monitoring stations, indoor air quality monitoring, industrial production, and other fields.
Common types of laser dust sensors
The following content is mainly divided based on detection principle, application scenario, and light source type.
Classification by detection principle
Laser scattering type: It detects concentration through the scattering signal generated by the interaction between the laser and particles, which is the mainstream type on the market.
Laser absorption type: It uses a laser to measure the difference in the absorption characteristics of particles.
Light scattering type: It belongs to the subdivision type of laser scattering, focusing on the detection of specific scattering patterns.
Classification by application scenario
Portable/fixed: Portable and suitable for rapid on-site detection, with small size and high precision, it can be easily integrated into smart devices. It is mostly used in air purifiers and HVAC systems. The GP2Y1010AU0F in OFweek Mall is a compact optical dust sensor.
Fixed type is mostly used for long-term monitoring, such as laser dust sensors used in industries such as mining, construction, and pharmaceuticals.
Online/Offline: Online is used for real-time monitoring, and offline is used for batch analysis.
Light source type
Infrared (IR) dust sensor
Infrared sensors use infrared light, which is generally less accurate and may not reliably detect particles smaller than PM2.5. For example, the MPM20-AH Infrared particulate matter sensor.
Laser particle sensor
Uses a focused and stable laser light source to sense dust particles. It is extremely accurate and can detect particles as small as PM0.3, and provides digital readings of PM1.0, PM2.5, and PM10 concentrations.
There are more than fifty laser dust sensors for users to choose from in OFweek Mall, with detailed specification sheets, and the original manufacturers supply wholesale at affordable prices.
