DFRobot Gravity SGP40 Air Quality Sensor

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.SpecificationsInput Voltage (V)3.3~5Current Consumption (mA)2.6Response Time2SInterface TypeI2COperating Temperature Range (掳C)-10 to 50Working Humidity Range0-100%RHDetecting Range0-1000 ppmLength (mm)22Width (mm)20Shipment Weight0.02 kgFeatures:Ultra-low power consumption(2.6mA)Built-in temperature and humidity compensation, no need to calibrateVOC index for direct air quality indicationPackage Includes:1 x Gravity: SGP40 Air Quality Sensor1 x Gravity-4P I2C/UART Sensor Cable
