➀ Infineon Technologies AG has launched a new XENSIV PAS CO2 5V sensor to improve building energy efficiency. The sensor uses Photoacoustic Spectroscopy (PAS) technology to tailor ventilation based on real-time occupancy, reducing carbon emissions and improving indoor air quality. It is suitable for HVAC systems, room controllers, and thermostats in both commercial and residential settings. ➁ The sensor delivers real-time, accurate air quality data, with a compact size and a fast response time. It is dust-proof and complies with the WELL TM Green Building Standard. ➂ All key components of the sensor are developed internally, and it offers configuration options for power consumption management.
