Description
The BME680 environmental sensor from Bosch is a 4-in-1 integrated sensor that contains temperature, humidity, barometric pressure, and Volatile Organic Compounds (VOCVolatile Organic Compound) gas air quality sensing capabilities in the same package. The BME680 has a small Metal Oxide (MOXMetal-Oxide) sensor, where the heated metal oxide changes its resistance depending on the amount of VOCs, such as Ethanol, Alcohol, and Carbon Monoxide, in the air. The output of the MOX sensor is one resistance value giving you the overall VOC content (it cannot differentiate different gases).
The BME688 environmental sensor from Bosch is an updated drop-in replacement for the BME680 with the additional gas scanning functionality to detect the presence of Volatile Sulfur Compounds (VSCVolatile Sulfur Compoundss) such as hydrogen sulfide (H2S) compounds and the capability of programming the gas sensor for controlled odor-analysis.
