BME680The BME680 is the first gas sensor that integrates high-linearity and high-accuracy gas, pressure, humidity and temperature sensors. It is especially developed for mobile applications and wearables where size and low power consumption are critical requirements. The BME680 guarantees - depending on the specific operating mode - optimized consumption, long-term stability and high EMC robustness. In order to measure air quality for personal wellbeing the gas sensor within the BME680 can detect a broad range of gases such as volatile organic compounds (VOC).Features:Personal air quality trackerAir quality mappingBattery Charging (LiPo 3.7V)USB-C Power INAir quality inside cars & public transportEnhanced context awarenessAccurate step & calorie trackerQuick GPS-fix & improved navigationIndicator of too high / low humidityAir quality & well-being indicatorSleep / recovery trackerWeather trendStair counterFloor level detectionTechnical SpecsSupply voltage VDD1.2 ... 3.6 V1.71 ... 3.6 VInterfaceI2C and SPIAverage current consumption(1Hz data refresh rate))Average current consumption in sleep mode2.1 μA at 1 Hz humidity and temperature3.1 μA at 1 Hz pressure and temperature3.7 μA at 1 Hz humidity, pressure and temperature0.09?12 mA for p/h/T/gas depending on operation modeGas sensorResponse time (τ 33-63%)Sensor-to-sensor deviationPower consumptionOutput data processing< 1 s (for new sensors)+/- 15% +/- 15< 0.1 mA in ultra-low power modedirect output of IAQ: Index for Air QualityHumidity sensorResponse time (τ0-63%)Accuracy toleranceHysteresis8 s± 3 % relative humidity≤ 1.5 % relative humidityPressure sensorRMS NoiseSensitivity ErrorTemperature coefficient offset0.12 Pa (equiv. to 1.7 cm)± 0.25 % (equiv. to 1 m at 400 m height change)±1.3 Pa/K (equiv. to ±10.9 cm at 1°C temperature change)Programming Guide:Pressure measurementPressure measurement can be enabled or skipped. When enabled, several oversampling options exist. The pressuremeasurement is controlled by the osrs_p<2:0> setting which is detailed in Section 5.3.2. For the pressure measurement,oversampling is possible to reduce noise. The resolution of the pressure data depends on the IIR filter (see Section 5.3.2.4)and the oversampling setting:When the IIR filter is enabled, the pressure resolution is 20 bitWhen the IIR filter is disabled, the pressure resolution is 16+ (osrs_p-1) bit, e.g. 18 bit when osrs_p is set to '3'Using the variables listed in Table 12, the following code will calculate the compensated pressure value in Pascal). It is,however, recommended to use the sensor API available on github (Chapter 4) for a friendlier user experience.Measurement flowReferring to Figure 1, the BME680 measurement period consists of a temperature, pressure and humidity measurement with selectable oversampling. Moreover, it contains a heating phase for the gas sensor hot plate as well as a measurement of the gas sensor resistance.After the measurement period, the pressure and temperature data can be passed through an optional IIR filter, which removes short-term fluctuations. For humidity and gas, such a filter is not needed and has not been implemented.Temperature measurementTemperature measurement can be enabled or skipped. Skipping the measurement is typically not recommended since temperature information is used to compensate temperature influences in the other parameters. When enabled, several oversampling options exist. The temperature measurement is controlled by the osrs_t<2:0> setting which is detailed in Section 5.3.2.2. For the temperature measurement, oversampling is possible to reduce the noise. The resolution of the temperature data depends on the IIR filter (see Section 5.3.2.4) and the oversampling setting:When the IIR filter is enabled, the temperature resolution is 20 bitWhen the IIR filter is disabled, the temperature resolution is 16+ (osrs_t-1) bit, e.g. 18 bit when osrs_t is setComponents Details:Battery Management System: ( MCP73831) The MCP73831 devices are highly advanced linear charge management controllers for use in space limited, cost-sensitive applications.
