Gravity: CCS811 Air Quality Sensor [Discontinued] _RPI_HAT_Inputs and uses fewer pins toThe DFRobot Gravity: CCS811 Air Quality Sensor can measure the eCO2 (equivalent CO2) and TVOC (Total Volatile Organic Compounds) density. It can be used in applications such as air quality detection, air purifiers, ventilation system and so on. This CCS811 air quality sensor uses AMS's unique micro hot plate technology. Compared to conventional gas sensors, the heating wire is lower power consumption, heating faster, and smaller. Internally integrated
