Product description
The SparkFun Indoor Air Quality Sensor - SCD41, SEN55 (Qwiic) combines two excellent indoor air quality sensors, the SCD41 and SEN55 from Sensirion. These sensors provide a comprehensive indoor air quality sensor that measures CO2, Volatile Organic Compounds (VOCs), particulate matter, temperature, and relative humidity.
The SCD41 uses Sensirion's PASens photoacoustic measurement system, which combines narrow-band IR light and a microphone inside the sensing package to detect concentrations from 0 to 40000 ppm with high accuracy over 400-5000 ppm ±(40 ppm+5%).
The SEN55 environmental sensor node uses Sensirion's proprietary algorithms to provide straightforward integration into various air quality monitoring applications. The sensor measures particulates of the following size specifications: PM1, PM2.5, PM4, and PM10 from a concentration of 0 to 1,000 µg/m3.
