MOx sensors, sometimes called chemiresistive sensors, are well known for their ability to offer affordable, reliable performance in harsh applications compared to non-MOx sensors. MOx materials and appropriate deposition methods that have a long history of use in critical applications with well-documented stability and reliability.

Renesas' Digital Gas Sensor ZMOD family provides a range of integrated digital sensor modules that provide best-in-class performance and reliability stability. In addition to being chemically and electrically calibrated, the platform’s flexible interface enables embedded AI and neural network trained software for configurable indoor, outdoor, and refrigeration air quality sensing solutions for sensing VOCs, ozone (O3), and nitrogen dioxide (NO2) gases.

Renesas has a rich history of shipping precision ASICs that are accurate, energy-efficient, and provide maximum flexibility through software-configurability. The combined experience of both sensing materials and sensing controls has created the industry’s most accurate and flexible gas sensing platform.

Renesas' ability to provide a configurable sensing platform comes from three factors: materials, temperature, and time. The MOx material delivers outstanding sensitivity to air quality contaminants, with a well-controlled manufacturing process developed and demonstrated over many years. Renesas' ability to vary the operating temperature and time at temperature comes from our innovative ASIC. These three parameters create a tunable system for reliable detection of a wide range of air contaminants. Our ZMOD platform can leverage critical parameters based on target gases to optimize sensitivity and provide the ultimate firmware-enabled gas detection platform. Renesas' advanced manufacturing supply chain, calibration for consistency, and JEDEC-based qualification ensure the best results for our customers.
