8-in-1 indoor air quality (IAQ) composite sensor

Cubic AM2020DY integrated air quality sensor module,is a highly integrated multi-parameter sensing solution that realize simultaneously particulate matter, VOC, NO2, HCHO and temperature and humidity measurement. 

AM2020DY adopts a light scattering technology to accurately detect particle matter and outputs PM mass concentration down to 0.3 μm. Based on MEMS MOX technology, it realizes high sensitivity to a wide range of volatile organic compounds—including benzene, ethanol, formic acid, and nicotine—as well as NO2 detection. It further adopts the electrochemical technology for HCHO detection, providing high selectivity and long-term stability.

Incorporating a matrix-based calibration system and optimized data algorithms, AM2020DY achieves high accuracy, cross-parameter consistency, and robust environmental adaptability. A dedicated temperature compensation model minimizes the impact of ambient conditions on measurement results.  The module delivers high accuracy, high sensitivity, and fast response, providing real-time outputs of multi-parameters. Long-term stability and repeatability make it a reliable sensing foundation for devices that require consistent indoor air quality data.

Designed with a compact, space-efficient structure, it enables easy installation in air purifiers, air quality monitors, air conditioners, ventilation systems, and various consumer electronics. Communication interfaces such as UART or I²C ensure effortless system integration with a wide range of controllers and smart devices, supporting data acquisition and air-quality-driven control strategies in real time.

With its high level of integration, stable multi-gas detection, and accurate PM sensing capabilities, AM2020DY is an ideal IAQ sensing module for applications across air purification, ventilation, environmental monitoring, and smart home industries—enabling comprehensive and reliable indoor air quality monitoring in modern buildings.
