Adafruit SCD-30 NDIR True CO2 Temperature and Humidity Sensor - STEMMA QT / Qwiic

Take a deep breath in...now slowly breathe out. The Adafruit SCD-30 is a true NDIR CO2 sensor that measures carbon dioxide concentration in ambient air with an integrated temperature and humidity sensor for compensation and additional environmental data. Perfect for environmental sensing, scientific experiments, air quality, and ventilation studies.

• NDIR True CO2 sensor technology for accurate CO2 measurement (400 ppm – 10,000 ppm)
• Integrated SHT31 temperature and humidity sensor
• Dual-channel detection for superior stability
• Accuracy: ±(30 ppm + 3%)
• Current consumption: 19 mA @ 1 measurement per 2 seconds
• Fully calibrated and linearized
• I2C digital interface with address 0x61
• STEMMA QT / Qwiic connectors for easy, solderless interfacing
• Compatible with 3.3V and 5V systems (level shifting and voltage regulator included)

The sensor is mounted on a compact 51.0mm x 25.4mm x 8.8mm PCB and comes with Arduino and Python/CircuitPython libraries and example code to get started quickly.
