PIMORONI BME688 4-in-1 Air Quality Breakout (Gas, Temperature, Pressure, Humidity)

The BME688 is the first gas sensor with Artificial Intelligence (AI) and integrated high-linearity and high-accuracy pressure, humidity and temperature sensors. It is housed in a robust yet compact 3.0 x 3.0 x 0.9 mm³ package and especially developed for mobile & connected applications where size and low power consumption are critical requirements. The gas sensor can detect Volatile Organic Compounds (VOCs), volatile sulfur compounds (VSCs) and other gases such as carbon monoxide and hydrogen in the part per billion (ppb) range.Additionally to all features of the BME680, the BME688 has a gas scanner function. In standard configuration, the presence of VSCs is being detected as indicator for e.g. bacteria growth. And the gas scanner can be customized with respect to sensitivity, selectivity, data rate and power consumption as well. The BME AI-Studio tool enables customers to train the BME688 gas scanner on their specific application, like in home appliances, IoT products or Smart Home.SpecificationsModelBME688Product Type4-in-1 Air Quality Breakout (Gas, Temperature, Pressure, Humidity)Operating Voltage(V)1.71 V to 3.6 VOperating Current (A)3.1 µAInterfaceI²C (up to 3.4 MHz) and SPI (3 and 4 wire, up to 10 MHzOperating Temperature (°C)-40 to 85 °CStandard Scan Speed10.8 s / scanPower Consumption (Watt)< 0.1 mA in ultra-low power modeAccuracy tolerance±3% r.H.Response time~8 sDimensional Accuracy (mm)3.0 mm x 3.0 mm x 0.93 mmShipment Weight0.004 kgFeatures:Bad breath or spoiled food detection based on the measurement of volatile sulfur compounds, which are an indicator of bacteria growthDetection of unusual gases and smells, which might indicate for instance a leakage or fireDiaper state detection, e.g. for baby careEarly detection of odors & bad smellsWildfire detectionReverse polarity protection (on Breakout Garden connector)Raspberry Pi-compatible pinout (pins 1, 3, 5, 7, 9)Compatible with ArduinoCompatible with Raspberry Pi (Python library)Compatible with Raspberry Pi Pico (C /Micro Python libraries)Packages Includes:1 x PIMORONI BME688 4-in-1 Air Quality Breakout (Gas, Temperature, Pressure, Humidity)
