Overview
Carbon dioxide is a key indicator of indoor air quality that damages human cognitive ability and happiness. SCD40/SCD41 is Sensirion's next-generation miniature carbon dioxide sensor. SCD40/SCD41 has high precision and high cost performance. The module is powered by a 2.54mm pitch pin header interface. The on-chip temperature and humidity compensation is realized by the built-in temperature and humidity sensor to achieve humidity and temperature measurement. The SCD40/SCD41 can intelligently adjust the indoor ventilation system according to the carbon dioxide concentration. The indoor air quality helps to reduce the carbon dioxide concentration for a period of time. Maintain a healthy, productive environment.
