      How A Photo-acoustic CO2 Sensor Works - Gravity: I2C SCD41 Infrared CO2 Sensor (400 - 5000 ppm)

      This project creates a portable CO₂ detection card using the SCD41 infrared photo-acoustic sensor, replacing bulky NDIR systems with MEMS microphones to shrink optical chambers for compact design. It delivers ±(40 ppm + 5% MV) accuracy in 400-5000 ppm range, enabling lightweight monitoring while requiring minimal environmental interference (vibrations, heat).
