| Soldered SCD43 CO2 Sensor Breakout |
The SCD43 is a CO2 sensor by Sensirion that simultaneously measures CO2 concentration (400–5000 ppm), temperature, and relative humidity over I2C. It uses Sensirion's PASens® photoacoustic sensing principle and includes an on-chip automatic self-calibration algorithm for long-term stability without user intervention. This library provides a simple Arduino-friendly wrapper around the Sensirion driver, supporting periodic measurements, low-power periodic mode, single-shot mode, and full sensor configuration. The board uses the Qwiic ecosystem connector for easy, solderless I2C connection.
