Recently, Lei Jun released a message on his official micro-blog: the millet air purifier is 5 years old, and the cumulative global sales have exceeded 10 million units, which has become the industry's "National Choice".
China's air purification industry in the past few years is like a roller coaster, between 2014 and 2016, because of the increasing severity of the haze and the constant attention of the media, almost zero Chinese air purification market ushered in a big outbreak of a period of time when the supply of air purification products was insufficient to meet the demand. With the improvement of air quality, the air purification industry has suffered a lot, while Xiaomi has issued dazzling sales figures in this cold winter when everything seems to be silent. There is still a lot of room for improvement in the consumption level of the air purification industry, and Chinese consumers are in the middle of considering purifiers as a way to "satisfy their needs" and "improve their quality of life". Some people think that air purification products are to deal with hazy weather, while others think that air purification products are a necessity to improve the quality of life. Consumers are beginning to have a sense of quality consumption, but it is not complete, after the tipping point of the intermediate state, it is a consumer market with unlimited potential.
Air purifier in terms of ordinary consumers, a very intuitive feeling is the product prompted by the concentration of dust, dust concentration is detected by the air purifier built-in dust sensors, therefore, dust sensors have gradually attracted the attention of the industry, the purifier is open or mode of the dust sensor sensing the concentration of dust in the air and decided, is the most direct link between the air purifier products and users. Driven by market demand, dust sensor technology is developing rapidly, while the dust sensor market is also exciting, new products, infrared dust sensors, laser dust sensors, how to choose a dust sensor to help air purifier products to enhance the user experience?
Infrared dust sensor
Built-in infrared light tube and photoelectric receiver tube, passive airflow through the detection area, infrared light irradiation in the particle group on the particles produced by the concentration of particles proportional to the scattered light, while the photoelectric tube will be converted to electrical signals, and through the amplification, filtering circuits and microprocessor output signals.
Laser Dust Sensor
Built-in fan can be active air intake, laser diode emitting laser irradiation on a single suspended particles to produce its particle size proportional to the scattered light, at the same time photocell in a particular angle will be converted to electrical signals, through the amplification and filtering and microprocessor processing, access to a fixed period of time particles size distribution, and through the MIE algorithm is converted to particulate matter mass concentration.following laser dust sensor entered the civilian field ,infrared dust sensor were used in a large number of air purifiers .owe to the development of the air purifier industry laser dust sensor have been mas product and the cost of laser dust sensor id gradually decreasing while the end produced and named measurement of dust sensors entered the civilian field, infrared dust sensors were used in a large number of air purifiers. However, with the development of the air purifier industry, laser dust sensors have been mass-produced, and the cost of laser dust sensors is gradually decreasing, while the end customer's demand for accurate measurement of air quality is also getting higher and higher. The adoption of laser sensors to accurately quantify airborne dust has been a recognized trend in the industry.
Following the launch of infrared dust sensors widely used in the air purification industry, laser dust sensors are also gradually being recognized by the market. In the future, Audiowell will continue to invest more research power in the air purification industry, and the upcoming new products include carbon dioxide concentration sensors, air monitoring boxes, and air management boxes, so please look forward to them!
