Infineon Unveils XENSIV PAS CO2 5V Sensor for Energy-Efficient Buildings
Infineon Technologies AG has unveiled the XENSIV PAS CO2 5V sensor, a compact, energy-efficient device designed to optimise energy consumption in buildings based on occupancy levels. Released in September 2025, this innovative sensor is set to revolutionise smart home and IoT applications, meeting the performance criteria of the WELL Green Building Standard.
The XENSIV PAS CO2 5V sensor is based on photoacoustic spectroscopy (PAS) technology, providing real-time air quality data with a fast response time of just 55 seconds. Its miniaturised form factor and multiple interfaces make it easy to integrate into various systems, including HVAC systems, room controllers, and IoT devices. The sensor is dust-proof and features a dedicated microcontroller for advanced compensation algorithms, offering versatile configuration options.
Andreas Kopetz, VP of ambient sensing at Infineon, emphasises the importance of CO2 sensors in smart homes and buildings. He notes, 'CO2 sensors play a vital role in monitoring air quality and enabling significant energy savings.' The sensor's easy assembly, even in high-speed, high-volume manufacturing, ensures widespread adoption.
The XENSIV PAS CO2 5V sensor from Infineon Technologies AG is poised to enhance energy efficiency in buildings, contributing to decarbonisation efforts. Its compact size, energy efficiency, and real-time data capabilities make it an ideal choice for smart home and IoT applications, while its compliance with the WELL Green Building Standard ensures it meets high-performance criteria.
