Seeed Studio 114992989 - Grove - Air Quality Sensor(BME688) with built-in AI, High-Performance 4-in-1, Gas, Humidity, Pressure and Temperature sensor

BME688 is the first gas sensor with Artificial Intelligence(AI) and integrated high-linearity and high-accuracy pressure, humidity and temperature sensors which can be easily customized for specific use cases such as the detection of odors & bad smells & wildfires, etc. It can measure humidity with ±3% accuracy, barometric pressure with ±1 hPa absolute accuracy, and temperature with ±1.0°C accuracy

It carries an extra gas scanning function with low power consumption (3.9 mA in standard gas scan mode). It can detect a wide variety of volatile organic compounds (VOCs), volatile sulfur compounds (VSCs), and other gases such as carbon monoxide and hydrogen in the part per billion (ppb) range. In standard configuration, the presence of VSCs is detected as an indicator for e.g. bacteria growth. The gas scanner can be customized with respect to sensitivity, selectivity, data rate and power consumption as well.

This new BME688 is ideal for innovative custom applications such as detecting food spoilage or timely detection of wildfires by measuring current gases and tracking changes in temperature and humidity. The artificial intelligence capabilities of the sensors and Bosch Sensortec's new BME AI-Studio software tool allow customers to quickly develop custom solutions directly for their specific use cases.

Features

  • The first gas sensor with AI: Trainable to detect different gas mixtures and their presence (e.g. coffee) with Bosch's AI Studio
  • High-performance 4-in-1 environmental sensor: Detect gas, humidity, temperature, and barometric pressure sensing in a compact size
  • Detect a wide variety of gases: Volatile organic compounds (VOCs), volatile sulfur compounds (VSCs), and other gases such as carbon monoxide and hydrogen in the part per billion (ppb) range
  • High accuracy: Measure humidity with ±3% accuracy, temperature with ±1.0°C accuracy, +-1C and barometric pressure with ±1 hPa absolute accuracy
  • Easy to use: Compatible with Grove port, just plug-and-play

Applications

  • Indoor and outdoor air quality measurement
  • Bad breath or spoiled food detection based on the measurement of volatile sulfur compounds, which are an indicator of bacteria growth
  • Detection of unusual gases and smells, which might indicate for instance a leakage or fire
  • Diaper state detection, e.g. for baby care
  • Early detection of odors & bad smells
  • Wildfire detection
