SCD40 SCD41 gas sensor module detects CO2 carbon dioxide temperature and humidity in one sensor I2C communication

Carbon dioxide is a key indicator of indoor air quality that impairs human cognitive ability and well-being, SCD40/SCD41 is the next generation of miniature carbon dioxide sensors, SCD40/SCD41 has high precision and cost-effective, the module with 2.54mm pitch pin interface to lead the power supply and communication pins. On-chip temperature and humidity compensation is realized by the built-in temperature and humidity sensor to measure humidity and temperature. The SCD40/SCD41 enables intelligent regulation of indoor ventilation systems based on CO2 concentrations, and indoor air quality helps maintain a healthy, productive environment with low CO2 concentrations over a period of time.
