A dust sensor is a sensor that detects the concentration of particulate matter in the air. It can detect particles with a diameter greater than 0.5 micrometers. Through the principle of light scattering, it detects the concentration of particles in the air and outputs digital data. PM2.5 refers to particulate matter with a diameter of 2.5 micrometers or less. Since these particles can enter the human lungs directly and easily trigger various lung and vascular diseases, filtering PM2.5 has a significant impact on human health.

As people's environmental awareness grows, the harmful effects of PM2.5 have gained public attention. In addition to protecting the environment to reduce the production of PM2.5, more products for filtering dust from the air are emerging. For instance, smart air conditioners and air purifiers are equipped with dust sensors to detect PM2.5 concentrations and dust filtration functions. They can detect and transmit PM2.5 levels for screen display and improve air quality by automatically starting or closing the air purification function.

Guangzhou Luftmy is a professional manufacturer focused on the R&D, production, and sales of PM2.5 sensors. We produce and sell both infrared dust sensors and laser dust sensors. Our sensors possess nationally certified invention patents and world-leading calibration technology. Our products feature high precision, strong stability, and excellent consistency.
