Description
With the well-liked ENS160 and BME280 ICs, the SparkFun ENS160/BME280 Environmental Combo Breakout takes care of all your atmospheric-quality sensor needs. A variety of environmental variables, such as the AQI, TVOCs, equivalent CO2 (or eCO2) levels, barometric pressure, humidity, and temperature, are provided by this special breakout. Using our convenient Qwiic system, all communication is done only via I2C to make using this breakout even simpler. However, we still have broken-out pins with a 0.1-inch spacing if you would rather use a breadboard.
The popular CCS811 sensor has been replaced by the ENS160, which measures total volatile organic chemicals in parts per billion (PPB) and equivalent CO2 (eCO2) in parts per million (PPM). An additional feature of the sensor is the Air Quality Index (AQI). If the ENS160 can access the current temperature and humidity, it also includes a capability that lets it adjust its readings. Fortunately, the BME280 offers temperature, barometric pressure, and humidity! As a result, the sensors can cooperate to provide us with measurements that are more accurate than they otherwise could.
