Product introduction Carbon dioxide is a key indicator of indoor air quality that impairs human cognitive ability and happiness. SCD40/SCD41 is Sensirion's next generation micro carbon dioxide sensor, which has high precision and cost-effectiveness. The module uses 2.54mm spacing pin interfaces to lead out power and communication pins. On chip temperature and humidity compensation is achieved through built-in temperature and humidity sensors for humidity and temperature measurement. SCD40/SCD41 can achieve intelligent adjustment of indoor ventilation systems based on carbon dioxide concentration, and indoor air quality helps to maintain a healthy and efficient environment under low carbon dioxide concentration for a period of time. feature Reference accuracy, specified range,
