The SGP40 Air Quality sensor adopts the new SGP40 digital VOC sensor chip launched by the well-known Sensirion. Based on the Sensirion’s CMOSens® technology, the SGP40 offers a complete sensor system on a single chip, a temperature-controlled micro-hotplate and a humidity-compensated indoor air quality signal. In combination with Sensirion’s powerful VOC algorithm, the sensor signal can be directly used to evaluate indoor air quality. It features low power(2.6mA), fast response(2s) and small size. The data from the sensor can be directly used to evaluate air quality without calibration.Integrated with an easy-to-connect Gravity interface, this Gravity SGP40 Air Quality sensor is very suitable for indoor projects that will be used for a long time, such as refitting air purifiers, kitchen hoods, etc. Besides, we provide you with C and Python libraries for use with different main-controllers.Note: VOC index is obtained by converting the detected ethanol equivalent in air.Features:Ultra-low power consumption(2.6mA)Built-in temperature and humidity compensation, no need to calibrateVOC index for direct air quality indicationApplications:Air PurifiersKitchen HoodsDemand-controlled VentilationThermostatsIndoor Air Quality MonitoringSpecification:Power Supply: 3.3V~5VOperating Current: 2.6mAPreheat Time: 10SResponse Time: 2SCommunication: I2CI2C Address: 0x59Operating Temperature Range: -10~50Storage Temperature Range: 5~30Operating Humidity Range: 0%RH~90%RHVOC Index: 0-500Measuring Range: 0-1000ppm(Ethanol Equivalent)Dimension: 20*22mm/ 0.79*0.87”Documents:Product wikiProduct Includes:Gravity: SGP40 Air Quality Sensor x1Gravity-4P I2C/UART Sensor Cable x1
