Environmental (IAQ) Sensor Breakout - BME680 (Qwiic)
The BME680 from Bosch gives you environmental sensing in one small package. This sensor contains temperature, humidity, barometric pressure, and VOC gas sensing capabilities. All over SPI or I2C at a great price. Like the BME280 & BMP280, this precision sensor from Bosch can measure humidity with ±3% accuracy, barometric pressure with ±1 hPa absolute accuracy, and temperature with ±1.0°C accuracy.
The BME680 contains also a small MOX sensor. The heated metal oxide changes resistance based on the volatile organic compounds (VOC) in the air, so it can perform air quality measurements.
