High performance disruptive CO2 sensor based on photocoustic spectroscopy (PAS). This sensor leverages PAS technology to provide an exceptionally small, real CO2 sensor, overcoming the challenges of existing carbon dioxide gas detectors. The XENSIV PAS CO2 integrates on the PCB the photo-acoustic (PAS) transducer, including a detector, infrared source and optical filter, a MCU for signal processing and algorithms and MOSFET chip to drive the infrared source.
The integrated MCU runs ppm calculations as well as advanced compensation and configuration algorithms. The sensor uses a MEMS acoustic detector. The exceptional sensitivity of this acoustic detector coupled with integrated PCB design reduce space requirements by more than 75 percent compared to commercially available real CO2 sensors. Suitable for use in building automation, home appliances, smart home IoT devices, city management/ CO2 emissions control and In-cabin air quality monitoring unit applications.
