BME280 Humidity and Pressure Sensor¶
This sample application periodically reads temperature, pressure and humidity data from the first available device that implements SENSOR_CHAN_AMBIENT_TEMP, SENSOR_CHAN_PRESS, and SENSOR_CHAN_HUMIDITY. This sample checks the sensor in polling mode (without interrupt trigger).
Building and Running¶
This sample application uses an BME280 sensor connected to a board via I2C. Connect the sensor pins according to the connection diagram given in the bme280 datasheet at page 38.
Using CMake and ninja:
cmake -B build -GNinja -DBOARD=nrf52840_pca10056 samples/sensors/bme280 ninja -C build flash
To check output of this sample , any serial console program can be used.
This example uses
picocom on the serial port
$ sudo picocom -D /dev/ttyUSB0
