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:`nrf52_pca10040` board is used.
