About Yole Group

Detailed technology and cost comparison of five Single-Beam and Dual-Beam NDIR, Photoacoustic, and Thermal conductivity CO2 gas sensors from the main market players - Sensirion, AMS, and Cubic.

From outside air quality monitoring to ever more applications in indoor air quality at home or in any enclosed space (car, classroom, offices,…), the gas and particle sensor market is gaining momentum, with a forecast 2.9M$ revenues in 2029 from $1.7 in 2023 with a CAGR23-29 of 9%;

To encapsulate the increasing interest in CO2 gas sensors market, Yole SystemPlus provides a deep comparative review of the technology, supply chain, and cost of five CO2 gas sensors. The reference products come from the main suppliers in the market: Sensirion, Amphenol, and Cubic; and represent the Single- and Dual-Beam Nondispersive infrared CO2 sensors (NDIR), Photoacoustic, and Thermoconductive technologies. Yole SystemPlus has analyzed these CO2 gas sensor systems to provide insights into the module structure, and the integrated devices, their technologies, manufacturing process, and cost of production.

We overviewed the modules, and provided detailed teardown pictures. This report includes the study of the devices integrated in the CO2 gas system, their package, and the dies, furnishing detailed optical and scanning electrone microscope (SEM) pictures of the package, MEMS structures and cross-section. We’ve also identified the MEMS Manufacturing processes.

We note and compare technological and cost difference between the main competitors as well as their supply chain choice. The report provides the comparison of the Sensirion thermopile sensor integrated in its own system with the Heimann Sensor solution integrated in Cubic and Amphenol CO2 gas systems.

Moreover, the report shows that the photoacoustic CO2 gas sensor is more economically beneficial compared to Single- and Dual-Beam NDIR which makes it very competitive in terms of cost and size.
