Infineon’s new PASCO2V15 sensor, based on photoacoustic spectroscopy (PAS), offers highly accurate carbon dioxide detection in building environments to improve air quality. The sensor architecture minimizes the need for optical components, enhancing stability and reducing size. It features pressure compensation capabilities, automatic baseline offset correction, and forced compensation for recalibration. The sensor operates on 5 V for the IR emitter and 3.3 V for digital components, with a peak current of 290 mA at 5 V and 10 mA at 3.3 V. The sensor consumes an average of 30 mW when performing one measurement per minute. PASCO2V15 enables real-time monitoring for smarter building automation and energy management.
