NG # 09440022-HW-SENS-022
SCD30 is a high-accuracy environmental sensor module that measures carbon dioxide (CO₂), relative humidity, and temperature. Based on non-dispersive infrared (NDIR) technology and Sensirion’s CMOSens® platform, it offers a CO₂ measurement range of 400–10,000 ppm with accuracy of ±(30 ppm + 3% of measured value). Its compact design and multiple communication interfaces make it ideal for indoor air quality monitoring, HVAC systems, and smart building applications.
