PM2.5 sensor

PM2.5 sensorIt is a device used to detect the concentration of fine particles (diameter ≤ 2.5 microns) in the air. Its core function is to capture the scattering, absorption, or reflection phenomena of particles on light through optical or electronic technology, and convert them into quantifiable electrical signals. The product has various forms, including independent modules, integrated sensors or embedded components, which can be adapted to air purifiers, fresh air systems, environmental monitoring stations and other equipment.

PM2.5 sensorApplication field

Smart Home: Embedded with air purifiers, fresh air systems, smart speakers and other devices to achieve automatic adjustment of operating modes or push air quality warnings.

Environmental monitoring: deployed at urban air quality monitoring stations, industrial parks, or transportation hubs to provide pollution tracing and control basis for environmental protection departments.

Industrial control: Monitor workshop dust concentration, prevent occupational diseases (such as pneumoconiosis) or explosion risks, and comply with safety production standards.

Health management: integrated into wearable devices (such as smartwatches) to help users avoid high pollution areas and adjust outdoor activity time.

Special scenario: Applied to dust intensive environments such as mines and construction sites, or places with high air cleanliness requirements such as hospitals and laboratories.

Product function

Real time monitoring: providing continuous and dynamic air quality data to help users or systems perceive pollution risks in a timely manner.

Decision support: Provide scientific basis for personal health protection (such as wearing masks), corporate emission control, or government pollution control.

Warning function: When PM2.5 concentration exceeds the standard, an alarm or linked device (such as starting a purifier or closing windows) will be triggered.

Data recording and analysis: Long term storage of historical data to assist in studying trends in air quality changes or the causes of pollution events.
