BME688 Environmental Sensor Module Temperature/Humidity/Pressure/Gas AI Smart I2C for arduino

BME688

Digital low-power gas, pressure, temperature and humidity sensors with artificial intelligence

BME688 is the first gas sensor to feature artificial intelligence (AI) and integrated high-linearity and high-precision pressure, humidity and temperature sensors. It is packaged in a robust and compact 3.0x 3.0x 0.9mm 3 package, specially developed for mobile and connected applications where size and power consumption are crucial requirements. This gas sensor can detect volatile organic compounds (VOCs), volatile sulfides (VSCs), carbon monoxide, hydrogen and other gases within the range of one part per billion (ppb).

In addition to all the functions of the BME680, the BME688 also features a gas scanner function. In the standard configuration, the presence of VSC is detected as an indicator of bacterial growth. In addition, the sensitivity, selectivity, data rate and power consumption of the gas scanner can also be customized. BME Al-StudioI enables customers to train the BME688 gas scanner on their specific applications, such as household appliances, Internet of Things products or smart homes.
