Gravity: I2C SCD41 Infrared CO2 Sensor (400 - 5000 ppm) _RPI_CASE_3APLUS 128x64 SH1106 Monochrome OLED displayCO2 is a key factor for indoor air quality as high levels compromise the human cognitive performance and well being. This Gravity: SCD41 CO2 sensor is based on the SCD41 miniature CO2 sensor from Sensirion. SCD41 builds on the photoacoustic NDIR sensing principle and Sensirions patented PAsens and CMOSens technology to offer high accuracy at an unmatched price and the smallest form factor. On chip signal compensation is realized with the built in
