Digital low-power gas, pressure, temperature and humidity sors with artificial intelligence. BME680 is the first gas sensor that integrates artificial intelligence (Al) with high linearity and high accuracy in pressure, humidity and temperature sensing. The design is compact and sturdy, and is particularly su itable for mobility and connectivity applications. In these applications, size and powerconsumption are key factors. Gas scanner function: In additionto having all the functions of BME680, BME688 also has the gas scanner function. Detection: In the standard configuration, the presence of (volatile sulfides) is detectedas an indicator of bacterial growth.
