SCD41 CO2 Sensor Breakout (Carbon Dioxide / Temperature / Humidity)

The SCD41 CO2 Sensor Breakout is a true carbon dioxide sensor that detects CO2 levels between 400 and 5,000 ppm. It is mounted on a Breakout Garden and is Qwiic/STEMMA QT-compatible, making it easy to integrate into various microcontroller projects.

This sensor uses advanced photoacoustic technology (PASens®) for high accuracy measurements of carbon dioxide, temperature, and relative humidity. It is suitable for monitoring air quality, ventilation efficiency, and occupancy in homes, workplaces, schools, and even industrial or laboratory settings.
