The XENSIV™ gas sensors family provides accurate and reliable solutions for detecting and measuring a wide range of gases, including CO2, hydrogen (H2), and refrigerants like A2L and A3. These advanced gas sensors are built on cutting-edge technologies to ensure optimal performance, making them ideal for applications in HVAC systems, automotive safety, industrial processes, and smart consumer devices.

With XENSIV™, Infineon combines expertise in gas sensor technology with a deep understanding of application needs, delivering energy-efficient, compact, and highly sensitive sensors. Perfect for integration into smart systems, XENSIV™ gas sensors enable precise gas detection and measurement, ensuring safety, compliance, and efficiency across various industries.

XENSIV™ CO2 sensors using Photoacoustic Spectroscopy (PAS)

One technology for measuring CO2 is the Photoacoustic Spectroscopy (PAS) principle, a method that allows for precise and reliable carbon dioxide detection. PAS works by absorbing specific wavelengths of light that cause the CO2 molecules to vibrate and produce sound waves. These sound waves are then detected by a sensitive microphone within the sensor. This technique is highly accurate because it directly measures the gas concentration, making it less susceptible to environmental factors such as humidity and temperature. 

Monitoring CO2 is crucial as high levels can indicate poor ventilation, leading to fatigue, headaches, and reduced cognitive function. Accurate CO2 detection ensures better indoor air quality in offices, schools, and homes.

CO2 sensors are also integral to HVAC systems for Demand Controlled Ventilation (DCV), optimizing energy efficiency by adjusting ventilation based on occupancy and CO2 levels. This not only improves air quality but also reduces energy consumption, making PAS-based CO2 sensors essential for modern building management.

XENSIV™ H2 sensors: Precise detection using Thermal Conductivity (TC)

Infineon's XENSIV™ H2 sensors use the Thermal Conductivity (TC) principle to detect hydrogen gas. By measuring the rate of heat conduction through the gas, these sensors identify hydrogen's high thermal conductivity, enabling precise detection of hydrogen concentration.

Monitoring hydrogen levels is critical due to its flammable nature. Infineon's H2 sensors provide real-time detection of hydrogen leaks and concentrations, ensuring safety in generation, production, storage, transportation, and utilization. This minimizes hydrogen losses and prevents accidents, making them ideal for automotive applications like fuel-cell electric vehicles (FCEVs) and hydrogen-based internal combustion engine (ICE) vehicles.

Additionally, they are valuable in battery electric vehicles (BEVs) for water intrusion sensing and early detection of thermal runaway in damaged batteries, as required by UNECE GTR 20 regulations. Beyond automotive, these sensors enhance safety in industrial applications, including hydrogen electrolyzers, storage, dispensers, fuel stations, and energy storage systems (ESS).

Refrigerant sensors: Safety solutions for HVAC and automotive systems

Infineon's XENSIV™ refrigerant sensors use the Thermal Conductivity (TC) principle to deliver high accuracy, robustness, and low power consumption for precise leak detection. These sensors are essential for HVAC systems, ensuring safety and efficiency in compliance with evolving regulations.

The Kigali Amendment, effective since 2019, mandates a gradual reduction of hydrofluorocarbons (HFCs) by 85% by 2045, driving the adoption of low-GWP refrigerants. Many of these alternatives, such as A2L refrigerant and A3 refrigerant, are mildly flammable, necessitating advanced leak detection systems. Standards like UL 60335-2-40 and IEC 60335-2-40 require Refrigerant Detection Systems (RDS) for specific refrigerant loads and room sizes, further emphasizing the need for reliable sensors.

XENSIV™ refrigerant sensors are vital across industries, including HVAC, cold storage, automotive, and industrial refrigeration. They ensure safety, efficiency, and compliance by detecting leaks in applications such as air conditioning, heat pumps, refrigerated transport, and data centers, safeguarding both people and the environment.
