Fermion - Air Quality Sensor - SGP40 - DFRobot SEN0392

Index: DFR-19376 EAN: 5904422348427
Air quality sensor from DFRobot. The module is equipped with the SGP40 chip produced by a popular company, which is Sensirion. Through the SGP40 system, the module measures the VOC air quality in the range from 0 ppm to 1000 ppm. Measured values are presented in the form of VOC index indications - taking the value from 0 to 500. Air quality depends on what range the reading is - the lower VOC index value the cleaner the air.

Product description: Fermion - Air quality sensor - SGP40 - DFRobot SEN0392

Air qualitysensor from the companyDFRobot. The module is equipped with a chipSGP40produced by a popular company, which is Sensirion. Through the SGP40 chip, the module measures the VOC air quality in the rangefrom 0 ppm to 1000 ppm. Measured values are presented in the form of VOCindex indications- taking the value from 0 to 500. Air quality depends on what range the reading is in - the lower VOC index value, the cleaner the air. The module uses theI2Cbus to communicate with the connected controller board. The longer thesensoris used, the better the sensitivity and accuracy of the trend and change. In an environment with potentially low air pollution, the sensor can obtain an accurate VOC indicator almost immediately after use. When measured in a heavily polluted environment, the sensor can obtain an accurate VOC indicator approximately 1 hour after being turned on.
