Adafruit SCD-30 - NDIR True CO2 Temperature and Humidity Sensor

The SCD-30 is a genuine NDIR CO2 sensor designed for precision atmospheric monitoring. Unlike VOC-based sensors, it directly measures CO2 concentration, making it ideal for environmental sensing and scientific experimentation.

Key specifications include a dual-channel detection system, with a measurement range from 400 ppm to 10,000 ppm, offering remarkable accuracy of ±(30 ppm + 3%). It features an integrated SHT31 temperature and humidity sensor, enhancing data reliability.

The sensor, operating over I2C, is compatible with a wide range of microcontrollers. With available Arduino and Python/CircuitPython code, integration is simple. The included STEMMA QT connectors ensure seamless connections, compatible with SparkFun Qwiic I2C connectors.

Built on a custom PCB, it includes a 3.3V regulator and level shifting, supporting both 3.3V and 5V systems. Extensive resources such as libraries and example code make it straightforward to start utilizing it in your projects.
