CO₂ Humidity and Temperature Sensor - SCD41 (Qwiic)
We have ✅ 1 available of the SF-SPX-18366 in our Sydney warehouse. An extra 3 units available with a short lead time.
A high-quality photoacoustic CO₂ sensor breakout based on the Sensirion SCD41, with integrated temperature and humidity sensing. The SCD41 detects CO₂ levels from 0 to 40,000 ppm with high accuracy over the 400–5,000 ppm range (±40 ppm + 5%). It also accepts ambient pressure readings for improved accuracy.
Features a Qwiic connector for plug-and-play I²C connectivity with no soldering required. An Arduino library is available for easy reading of CO₂, humidity, and temperature values.
