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.
