Does bme680 measure air quality?

One of the main features of the BME680 sensor is its ability to measure the air quality of indoor environments. That sounds great, until you realize, that the actual output of the BME680 is not a clear, easy-to-understand value like the IAQ-Index, but it delivers instead a resistance value in ohms. What a bummer!

What is a bme680 sensor?

The BME680 is an environmental sensor that combines gas, pressure, humidity and temperature sensors. The gas sensor can detect a broad range of gases like volatile organic compounds (VOC). For this reason, the BME680 can be used in indoor air quality control. Gas: Volatile Organic Compounds (VOC) like ethanol and carbon monoxide

What is the bme688 air quality sensor?

To address this growing need, Bosch Sensortec has announced the BME688, the first air quality MEMS sensor that combines gas, humidity, temperature and barometric pressure sensing with innovative artificial intelligence (AI) capability; essentially creating the world’s smallest four-in-one air quality measurement solution.

How does the bme680 detect VOCs?

The BME680 contains a MOX (Metal-oxide) sensor that detects VOCs in the air. This sensor gives you a qualitative idea of the sum of VOCs/contaminants in the surrounding air – it is not specific for a specific gas molecule. MOX sensors are composed of a metal-oxide surface, a sensing chip to measure changes in conductivity, and a heater.
