This little sensor contains temperature, humidity, barometric pressure, and VOC gas sensing capabilities. All over SPI or I2C at a great price!\u003c\/p\u003e\n\u003cp\u003eLike the BME280 \u0026amp; BMP280, this precision sensor from Bosch can measure humidity with ±3% accuracy, barometric pressure with ±1 hPa absolute accuracy, and temperature with ±1.0°C accuracy. Because pressure changes with altitude, and the pressure measurements are so good, you can also use it as an altimeter with ±1 meter or better accuracy!\u003c\/p\u003e\n\u003cp\u003eThe BME680 takes those sensors to the next step in that it contains a small MOX sensor. The heated metal oxide changes resistance based on the volatile organic compounds (VOC) in the air, so it can be used to detect gasses \u0026amp; alcohols such as Ethanol, Alcohol and Carbon Monoxide, and perform air quality measurements. Note it will give you one resistance value, with overall VOC content, but it cannot differentiate gasses or alcohols.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePlease note this sensor, like all VOC\/gas sensors, has variability and to get precise measurements you will want to calibrate it against known sources!\u003c\/strong\u003e That said, for general environmental sensors, it will give you a good idea of trends and comparisons. Adafruit recommend that you run this sensor for 48 hours when you first receive it to \"burn it in\", and then 30 minutes in the desired mode every time the sensor is in use. This is because the sensitivity levels of the sensor will change during early use, and the resistance will slowly rise over time as the MOX warms up to its baseline reading.\u003c\/p\u003e\n\u003cp\u003eFor your convenience they've pick-and-placed the sensor on a PCB with a 3.3V regulator and some level shifting, so it can be easily used with your favorite 3.3V or 5V microcontroller. All of the pins of the BME680 are available on standard 0.100”\/ 2.54mm pitch headers for use with a breadboard.
