The worsening global air pollution problem has prompted countries to invest significant resources in developing efficient air quality monitoring technologies. The Industrial Technology Research Institute (ITRI) has successfully developed domestically produced optical PM2.5 and O3 air quality sensors that not only perform exceptionally well but are also compact, resistant to interference, and suitable for mass production—making them highly compatible with IoT applications. Unlike traditional sensors, ITRI’s sensors incorporate an innovative optical design and patented mechanisms, significantly enhancing measurement accuracy and stability. Additionally, a rigorous calibration process and cybersecurity certification ensure data reliability and security. This breakthrough technology not only aids government efforts to enhance environmental monitoring capabilities but also supports businesses in autonomous management, laying a solid foundation for smart cities.
A New Era of Smart Air Quality Monitoring! ITRI’s Technology Boosts Industry Upgrades
The sensor employs optical simulation tracking within its optical sensing components to analyze light behavior within the cavity and confirm the divergence angle, enabling rapid insight into the optical response within the system. It features an LED micro-lens design that minimizes energy loss and boosts light collection efficiency. For circuit control, a single LED with a dual PD circuit design is used, incorporating a feedback control circuit and high-resolution ADC for LED current compensation control, which enhances light source stability and reduces noise interference. Third-party testing has shown that the sensor's resistance to humidity interference exceeds that of major international manufacturers by over sixfold and has passed the Ministry of Environment’s stringent outdoor type certification. This demonstrates that the sensor maintains high accuracy even in harsh environments, providing reliable air quality data. The sensor has also been successfully transferred to domestic manufacturers and secured multiple patents, underscoring its technological maturity and market potential.
The sensor, having passed the rigorous certification by the Ministry of Environment, has also been successfully exported overseas and can be widely applied in environmental law enforcement, smart cities, and corporate autonomous management. By leveraging IoT technology, the data collected by the sensor can be analyzed to accurately identify sources of air pollution, aiding the government in formulating more effective environmental policies. Additionally, businesses can use the sensor’s data to monitor air quality within their facilities in real-time and take appropriate corrective measures, enhancing product quality and reducing production costs.
ITRI's Chen Chih-Jen: Taiwan’s Air Quality Monitoring Technology Goes Global
Deputy Director Chen Chih-Jen stated that the team’s successful development of the air quality sensor technology not only fills a domestic technological gap but also possesses global competitiveness. Looking ahead, the team will continue refining the technology and expanding its applications to contribute to a healthier living environment. Deputy Director Chen emphasized that ITRI’s technology has garnered multiple patents and has been successfully transferred to domestic manufacturers, accelerating industry upgrades and transformation. Furthermore, ITRI is actively engaging in international collaborations, aiming to bring Taiwan’s air quality monitoring technology to the global stage. Through exchanges with international experts and joint development of advanced monitoring technologies, ITRI aims to contribute to global environmental protection efforts.
