Product description: Grove BME688 - AI 4 in 1 I2C sensor - gas, pressure, temperature and humidity - Seeedstudio 114992989
Grove series module equipped with BME688 sensor. It is the first sensor equipped with artificial intelligence (AI) that measures gas, pressure, temperature and humidity with high linearity and accuracy. The sensor allows you to measure temperature in the range from -40 ° C to 85 ° C , humidity from 0% to 100% and pressure from 300 hPa to 1100 hPa , as well as volatile organic compounds , volatile sulfur compounds and other gases such as carbon monoxide and hydrogen on a parts per billion (ppb) basis. The gas sensor can be "trained" by AI to detect different gas mixtures and their presence (e.g. coffee) using Bosch's AI Studio. It can be used to detect unpleasant odors, food spoilage, forest fires, etc. The communication module uses the I2C interface.
Module with BME688 sensor, the set also includes a Grove cable. 
Module pins.Main features of the BME688 sensor
- The first gas sensor with artificial intelligence . Trainable to detect different gas mixtures and their presence (e.g. coffee) with AI Studio from Bosch.
- High-performance 4-in-1 environmental sensor . Detects gas, humidity, temperature and barometric pressure.
- Detects a wide range of gases. Volatile organic compounds (VOCs), volatile sulfur compounds (VSCs) and other gases such as carbon monoxide and hydrogen in the parts per billion (ppb) range.
- High accuracy.
- temperature measurement: ±1.0°C
- humidity measurement: ±3%
- barometric pressure measurement with absolute accuracy: ±1 hPa
- Easy to use. Compatible with the Grove system - plug and play.
Application of the sensor
- Air quality measurement
- Detecting bad breath or spoiled food by measuring volatile sulfur compounds, which are an indicator of bacterial growth
- Detection of unusual gases and odors that may indicate, for example, a leak or fire
- Fire detection
