SCD41 CO2, temperature and humidity sensor module. It allows ambient carbon dioxide concentrations to be measured in the range from 400 to 5,000 ppm. In addition, it has an integrated temperature and humidity sensor, making it suitable for environmental sensing, scientific experiments and air quality studies. It can be used in systems with an operating voltage of 3.3 V or 5 V, and communication is via an I2C interface (Gravity connector). Full documentation and examples are available on the product page.
