SparkFun Environmental Sensor Breakout – BME680

SparkFun Environmental Sensor Breakout – BME680 combines a gas sensor with temperature, humidity, and barometric pressure sensing. The breakout is a complete environmental sensor in a single package. The gas sensor on the BME680 detects a wide variety of volatile organic compounds (VOC) to monitor indoor air quality. The BME680 combines precise temperature, humidity, and barometric pressure and works as a completely standalone environmental sensor.
