Carbon Dioxide Sensor Breakout (SCD41 / Temperature / Humidity) by Pimoroni

This is a genuine carbon dioxide sensor, capable of detecting CO2 levels from 400 to 5,000 ppm, mounted on a Breakout Garden and Qw/ST-compatible breakout. The SCD41 sensor, using photoacoustic technology, provides precise CO2 proportion readings in ppm, along with temperature and humidity measurements. High CO2 levels can lead to fatigue and reduced cognitive function. This sensor variant can detect up to 5,000 ppm, making it useful in various settings. During tests at Pimoroni HQ, it showed remarkable sensitivity to CO2 level changes. It's compatible with the Breakout Garden system and various microcontrollers with Qwiic or STEMMA QT connectors. Key features include a Sensiron SCD41 sensor, high accuracy, wide range, I2C interface, and compatibility with Raspberry Pi and Pi Pico. The kit includes the breakout board, headers, and software libraries for easy integration. Dimensions are approximately 24mm x 21mm x 8mm.
