This little BME688 sensor breakout contains temperature, humidity, barometric pressure, and VOC gas sensing capabilities with SPI or I2C interface. This precision sensor from Bosch can measure humidity with +-3% accuracy, barometric pressure with +-1 hPa absolute accuracy, and temperature with +-1.0C accuracy. Because pressure changes with altitude and the pressure measurements are so good, you can also use it as an altimeter with +-1 meter or better accuracy. The BME688 takes those sensors to the next step in that it contains a small MOX sensor. The heated metal oxide changes resistance based on the volatile organic compounds (VOC) in the air, so it can be used to detect gasses & alcohols such as Ethanol, Alcohol, and Carbon Monoxide, and perform air quality measurements.
