| Description |
| *********** |
| |
| This sample application periodically (every 3s) measures the ambient temperature |
| in degrees Celsius, atmospheric pressure in kilopascal, relative humidity in percentage, |
| and gas sensor resistance in ohms. The result is written to the console. |

| Wiring |
| ******* |
| |
| This sample uses the BME680 sensor controlled using the I2C interface. |
| Connect Supply: **VDD**, **VDDIO**, **GND** and Interface: **SDA**, **SCL**. |
| The supply voltage can be in the 1.8V to 3.6V range. |
| Depending on the baseboard used, the **SDA** and **SCL** lines require Pull-Up |
| resistors. |
| |
| Building and Running |
| ******************** |
| |
| This project outputs sensor data to the console. It requires a BME680 |
| sensor. It should work with any platform featuring a I2C peripheral interface. |
| It does not work on QEMU. |
| In this example below the :ref:`nrf52840dk_nrf52840` board is used. |
