PM2.5 sensors come in two types. One is the PM2.5 infrared dust sensor, which uses an infrared light source to analyze changes in scattered light caused by tiny particles in the air to determine particle concentration. The other is the PM2.5 laser dust sensor, which uses a laser light source. Its principle is similar to the infrared sensor but with higher accuracy, capable of detecting particle concentrations with diameters as small as 0.3μm.

Luftmy Intelligent Technology Co., Ltd. is a high-tech company specializing in sensor research, development, production, and sales. Currently, it mainly develops PM2.5 series infrared sensors, PM2.5 series laser sensors, and CO2 carbon dioxide sensors. Among them, the cost-effective and widely used HPD05 infrared sensor is our flagship product, featuring core technology from Germany and multiple patents. It is currently the most advanced PM2.5 infrared sensor in the market. Chinese companies’ PM2.5 sensor market share exceeds 50%, enjoying excellent reputation and high influence in the industry.
