SS-BME688 I2C - gas, humidity, temperature and pressure sensor

Module equipped with BME688, the first gas sensor with artificial intelligence (AI) and integrated humidity and temperature sensor with high linearity and high accuracy. The gas sensor is capable of detecting volatile organic compounds (VOCs), volatile sulfur compounds (VSCs) and other gases such as carbon dioxide equivalent (CO2e) and hydrogen in the ppb range. The BME688 sensor has high sensitivity and responds to most VOCs as well as many other air pollutant gases. The intensity of the signal changes with the reactivity of the chemical gases. The BME688 sensor measures temperature from -40°C to 85°C, humidity from 0% to 100%, and pressure from 300 hPa to 1100 hPa. The module uses an I2C interface for communication. It is powered by 3.3 V or 5 V.

• Temperature measurement range: from -40°C to 85°C
• Humidity measurement range: from 0% to 100%
• Pressure measuring range: from 300 hPa to 1100 hPa
• Main gas sensor outputs (via BSEC): IAQ, bVOC & carbon dioxide equivalent (CO2e) (ppm), gas scan result (%) & intensity level
• IAQ sensor to sensor deviation: +/- 15% / +/- 15 IAQ
• Relative humidity tolerance / hysteresis accuracy: +/- 3% / ≤ 1,5%
• Absolute temperature accuracy: +/- 0.5°C (at +25°C)
• Pressure measurement error: +/- 0,25%
