Gravity - Air Quality Sensor - SGP40 - DFRobot SEN0394

Index: DFR-19375 EAN: 5903351246279
Air quality sensor manufactured by DFRobot. It has a built-in SGP40 chip (introduced by the well-known Sensirion company), which measures the VOC air quality in the range from 0 ppm to 1000 ppm. The values are presented as VOC index readings - from 0 to 500. The air quality depends on what range the reading is in - the lower the VOC index value, the cleaner the air. The module uses I2C communication interface.

Product description: Gravity - Air Quality Sensor - SGP40 - DFRobot SEN0394

Air qualitysensor produced by DFRobot. It has a built-inSGP40chip (introduced by the well-known company Sensirion), which measures the VOC air quality in the rangefrom 0 ppm to 1000 ppm. The values are presented as VOCindexreadings - from 0 to 500. The air quality depends on what range the reading is in - the lower the VOC index value, the cleaner the air. The module usesI2Ccommunication interface. The longer thesensoris used, the better its sensitivity and accuracy of trend and change. In an average environment (with potentially low air pollution), the sensor can obtain an accurate VOC index immediately after use. Conversely, in a heavily polluted environment, the sensor may obtain an accurate VOC indicator approximately 1 hour after activation.
