Indoor air PM2.5 fine particles have an important impact on human health. Because the indoor environment is relatively smaller than the outdoors, it is easier to control. Therefore, using purification equipment such as air purifiers to carry out continuous monitoring and control of indoor PM2.5 can effectively improve indoor air quality, thereby enhancing the comfort of our living environment and protecting human health.

Compared with the outdoor atmospheric environment, the prevention and control measures for indoor air particulate pollution are more operable and easier to achieve. In the reality where outdoor pollution cannot be significantly improved in the short term, it is necessary to monitor the PM2.5 concentration of indoor air and implement control through corresponding purification means. The particulate PM2.5 detection sensor module is a key piece of equipment for monitoring indoor air pollution and improving indoor air quality. Users can choose the LUFMES infrared PM2.5 sensor module, which uses the principle of optical scattering to detect the concentration of dust in the air. It can be applied to air conditioners with purification functions, air purifiers, vehicle purification equipment, portable detectors, fresh air systems, smart detectors, etc.

Reliable performance and reasonably priced PM2.5 dust sensors are an important prerequisite for effectively controlling indoor PM2.5 concentrations. For particulate matter in the atmospheric environment, existing standards have put forward requirements for the installation and acceptance of continuous monitoring systems, and there are also devices based on the β-ray method and oscillating microbalance method used for atmospheric environmental monitoring. The monitoring of PM2.5 in indoor air has different requirements for PM2.5 sensor performance. For example, the LUFMES laser dust concentration sensor features small size, easy installation, and fast response. On the basis of reliable performance, particulate matter sensors suitable for indoor air monitoring are price-sensitive. Particulate matter laser sensors based on the principle of light scattering, with their advantages of small size, fast response, and low price, have been widely used in particulate matter detection for indoor environments such as air purifiers and fresh air systems.

Guangzhou LUFMES focuses on the technical research, production, and sales of optical particulate matter sensors. LUFMES infrared PM2.5 sensors, laser dust sensors, PM2.5 sensor modules, micro-dust sensors, particulate matter sensor modules, air quality sensors, and other gas sensors have received wide acclaim in the industry for multiple performance indicators such as measurement accuracy, stability, consistency error, and anti-interference.
