With air quality a major global concern, Samyoung continues improving its air quality sensors – Interview by Yole Développement

Outdoor air pollution is one of the 21st century’s major challenges, and air quality sensors are invaluable in terms of monitoring pollution and contributing to a better environment. Consumers desire the latest gas and particle sensors with air purifiers, and the car industry wants cutting-edge gas and particle sensors for in-cabin air quality and powertrain management.

Yole Développement recent report Gas and Particle Sensors 2018 forecasts that the gas and particle sensors market will reach $1.2B in 2023, with 300Munits (all applications included).

2018-2023 gas sensor market in value

With this in mind, i-Micronews Team is pleased to share with its readers Samyoung S&C’s present and future view of the gas and particle sensors market, through the interview of Sangick Park, CEO at Samyoung S&C, realized by Eric Mounier PhD, Fellow Analyst at Yole Développement. Discover teh content of their discussion.

Eric Mounier (EM): Can you update our readers on Samyoung S&C’s gas and particle sensor activities?

Sangick Park (SP): Since entering the fine-dust sensor market in the late 2000s, we have consistently improved our sensor performance. We strive to expand our solutions to major applications like home appliances and new IoT devices, in markets incuding China, Europe, and Korea.

We constantly refine our Combo Sensor, which combines fine-dust sensors and VOC sensors, in order to meet consumer needs and optimize product competitiveness. Specific to our VOC sensors, we are exploring the use of the digital-output model in silicon-based form (CHIP type), instead of the analog output model (CAN type) in the traditional ceramic-based semiconductor form.

With our own humidity-sensing technology, we seek to maximize competitiveness and provide a combined “indoor air-quality Sensing solution” that transcends standard fine-dust detection solutions.

To this end, Samyoung S&C plans to develop an integrated system-in-package (SIP) that can detect temperature, humidity, fine dust, and TVOC in order to provide an air-quality index, and eventually develop ultra-small, smart combination sensor modules with these capabilities.

EM: What applications drive the gas and particle sensor market?

SP: Beyond traditional consumer electronics, the market portends that an integrated air quality management solution, combined with the IoT industry, will rapidly emerge. For example, devices and facilities that can measure and detect the air quality of a large space will attract consumers’ attention.

With high-concentration fine dust becoming a social issue in Korea, specific legislative bills for dust management are being introduced. And with new national laws, we expect stronger demand for precision-sensing, cleanness, and clean technologies.

In the field of gas sensing, the populace is increasingly interested not just in VOC but also CO2. As these elements are integral to indoor air quality, the demand for gas sensors will increase grow just as fast as for fine dust sensors.

EM: Do you see geographical differences (i.e. the demand in Asia differs from that of Europe or North America)?

SP: The theory that most of the fine dust currently covering Korea comes from China is most convincing. Although the problem of air pollution due to fine dust is particularly noticeable in the Far East in countries like Korea, China, and Japan, it is hard to say that it’s limited to certain areas, since it is an environmental issue.

However, air pollution caused by massive forest fires like those which occurred recently in North America, and diesel car regulations that have intensified worldwide after originating in Europe, continue to increase related businesses in air-quality measurement, and the demand for clean functions.

EM: What separates Samyoung from the competition?

SP: Samyoung S&C has a unique sensing technology that measures different elements like humidity and fine dust. Our sensor calibration technology is a core source of our competitiveness, providing us with the necessary edge to compete with global sensor market leaders in meeting consumers’ various growing needs.

Additionally, our optical-sensor calibration technology, based on IR LED, is a key differentiator ensuring our competitiveness in the fine-dust sensor field. Using IR LEDs, which are similar to the laser diode-type that competes on the market, our products are gaining market confidence thanks to lower prices and a relatively longer lifecycle.

In order to reinforce and optimize the competitiveness of our products,
Samyoung S&C builds upon the following four core technologies:

  • (A) LED-based, light-scattering fine dust measurement technology for implementing fine particle detection
  • (B) Self-developed exclusive ASIC for combo sensor
  • (C) Capacitive temperature & humidity-sensor calibration technology (acquire AEC-Q100 certification)
  • (D) TVOC sensor technology and eCO2 sensor technology based on MEMS (MOx)

EM: Do you see market traction for combo sensors (different gases + particles)? For which applications?

SP: Similar to the market-leading applications mentioned above, we believe devices offering integrated air-quality management solutions will attract consumers’ interest in the future

Attention will be given not only to the precision detection of key elements like temperature, humidity, fine dust, TVOC, CO2, etc., but also to “clean facilities” that can effectively and efficiently improve the air quality of a given space. And since “air quality” is not limited to any particular country or region, solutions are likely to be developed and produced in various formats, independent of its shape.

Moreover, we expect to see user-interface diversification that enhances user-convenience for myriad sensor data needs, and not just measurement or cleanness.

In response to market demand, Samyoung S&C plans to develop an atmospheric-environment sensor node based on an on-demand semiconductor (ASIC)-type SIP (system-in-package), embedded with multiple sensing elements and multiple signal processes
