Product description: CCS811 - Clean Air Sensor - eCO2 / TVOC - I2C - DFRobot SEN0339
Sensorproduced by DFRobot company, equipped withCCS811chip. Allows you to measure the concentration of particleseCO2and volatile organic compoundsTVOCthat are in theair. The measurement range for eCO2 isfrom 400 ppm to 8000 ppm, and for TVOCfrom 0 ppb to 1100 ppb. The module uses the I2C bus to communicate with the controller module. It isArduinocompatible, connected using the included 2.54mm raster goldpin connectors. It can be poweredfrom 3.3V to 5V.
Compatible with Arduino
