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 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.

About Gas Sensors for Air Quality and Applications Leak Detection

A gas sensor is a device used to determine the presence and amount of a specific gas or gases. The gas sensor system is typically manufactured to detect a specific family of gasses or specific gas and convert that measurement into a resistive electrical signal that can be interpreted by the system. Several factors influence the quality of a gas sensor, including accuracy (how accurate is the measurement), sensitivity (detection of very low levels of gas), selectivity (how well it performs in the presence of other gases), and stability (how reliably it performs year after year).

Renesas' digital and analog gas sensors provide industry-leading specifications, addressing industrial leak detection and Air Quality including TVOC, O3 & NOx as well gasses found in refrigeration systems. Options are available for measuring the presence of hydrogen gas, methane gas, propane gas, liquefied petroleum gas (LPG.

MOx Sensor Technology Offers Superior Performance

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.
