Product description
SCD41 CO₂ is a sensor for measuring carbon dioxide (CO₂), temperature, and relative humidity. The module is based on the Sensirion SCD41, which uses photoacoustic sensing technology (PASens®) to provide accurate CO₂ measurements in the range of 400–5000 ppm. It is suitable for monitoring indoor air quality, ventilation systems, classrooms, offices, laboratories, and other applications where air quality measurement is required.
The board features an I2C interface and is equipped with a Qwiic connector for quick solderless connection. It can also be used directly with Raspberry Pi or Raspberry Pi Pico and is supported by Python, C++, and MicroPython libraries.
