Air quality monitoring is invigorating the sensor market! Air quality monitoring in automobiles, homes and other buildings is promoting the development of gas and particle sensor market. According to the 2014 report of the World Health Organization (who), outdoor air pollution is one of the main challenges in the 21st century, and about 4 million people around the world died there.
The impact of air quality monitoring on the gas and particulate sensor market
Another report shows that since 2016, more than 90% of the world's population has lived in areas with air pollution levels higher than the who limit. As a result, these have created a global driving force for the development and installation of gas and particle sensors. For a long time, the main gas and particle sensor market has been limited to industrial applications. But today, the decline in air quality affects many areas, including families, offices, hotels, cars and so on. Historically, gas sensors in buildings have been used to control air conditioning systems to achieve energy conservation and emission reduction.
Now, we have observed that the main function of gas sensors has changed from "comfort" to "safety" due to the residents' need for clean indoor air. The trend also extends to other environments, such as private cars and public transport, which has led to a growing market for gas sensor applications. Commercial vehicles are increasingly fitted with gas and particle sensors to ensure high quality air for passengers.
Gas sensor market size from 2018 to 2023
Although the gas and particle sensor market has a good prospect, the growth time of consumer market is longer than expected, which affects the market decision-making of many companies. For example, AMS emphasizes that it will not spend much effort to expand consumer applications in the short term. Thus, the expected smart phone integrated gas sensor is far away.
This report analyzes the impact of global air quality monitoring on each segment. The main parts affected are heating, ventilation and air conditioning (HVAC), consumer products, and comfort in transportation. Each segment describes in detail the technical requirements, gases to be tested, market forecasts, major suppliers and regulations. Yole predicts that the gas sensor market will reach US $1 billion in 2022. In addition, we have a chapter to discuss the development of combined environmental sensors and electronic nose technology. Although challenges remain, they are the next step in improving air quality sensing in a number of applications. MOS has finally found its application market. Optical technology has been used in particle sensing metal oxide semiconductor (MOS) for many years, but it is hindered by cross sensitivity, sensor drift and other problems. Now, the application of MOS technology has been greatly promoted due to two application drivers: Interior / exterior monitoring and air purifier. MOS is the best trade-off technology for "cost / size" of VOC gas sensor.
Market share of gas sensing technology in 2017
On the other hand, optics is the reference technology of particle sensing. Particle monitoring is becoming more important than gas sensing. More and more attention has been paid to the ultra-fine particles (PM1) with diameter less than 1 micron, because they are the most harmful "species". So most manufacturers are developing PM1 and below particulate matter sensors. The ecosystem of Asian manufacturers is growing rapidly because Asia is very concerned about air quality. It is estimated that in 2020, the air purifier market will achieve an annual shipment of 20 million units. China currently accounts for more than 95% of the global air purifier market. Most of these air purifiers integrate VOC and particulate matter sensors at the same time. As a result, Asian manufacturers are developing their own technology and product mix for the local market. They cover all gas and particle sensing technologies and vary from place to place.
Asian manufacturers in the field of gas and particle sensing technology layout
Intellectual property (IP) dynamics reflect Asia's strong interest in gas and particle sensors, as well as significant differences in technology and research and development. Since 2010, patent applications in China have increased significantly. On the contrary, patent activities in other countries are almost stable; since 2014, more and more Chinese companies and R & D laboratories have become new members of the patent field.
LUFTMY laser dust particle sensor LD15 is a high-precision particle concentration sensor based on Mie scattering theory. It can continuously collect and calculate the particle concentration distribution, and output in the form of general digital interface. LD15 has the characteristics of small volume, high precision, strong anti-interference ability, low power consumption, long service life, short response time of zero error alarm rate, and can be embedded in various instruments related to the concentration of suspended particles in the air, such as air purifier, PM2.5 detector, Haze Meter and other instruments or environmental improvement equipment, to provide timely and accurate concentration data.
