adafruit-circuitpython-bme280 2.6.3

CircuitPython library for the Bosch BME280 temperature/humidity/pressure sensor.

Introduction

I2C and SPI driver for the Bosch BME280 Temperature, Humidity, and Barometric Pressure sensor

Installation and Dependencies

This driver depends on:

• Adafruit CircuitPython

• Bus Device

Please ensure that the driver and all dependencies are available on the CircuitPython filesystem. This can be most easily achieved by downloading and installing the latest Adafruit library and driver bundle on your device.

Installing from PyPI

On supported GNU/Linux systems like the Raspberry Pi, you can install the driver locally from PyPI. To install for current user:

pip3 install adafruit-circuitpython-bme280

To install system-wide (this may be required in some cases):

sudo pip3 install adafruit-circuitpython-bme280

To install in a virtual environment in your current project:

mkdir project-name && cd project-name
python3 -m venv .env
source .env/bin/activate
pip3 install adafruit-circuitpython-bme280

Usage Example

import board
import time
import adafruit_bme280

# Create sensor object, using the board's default I2C bus.
i2c = board.I2C()   # uses board.SCL and board.SDA
bme280 = adafruit_bme280.Adafruit_BME280_I2C(i2c)
#or with other sensor address
#bme280 = adafruit_bme280.Adafruit_BME280_I2C(i2c, address=0x76)

# OR create sensor object, using the board's default SPI bus.
# SPI setup
# from digitalio import DigitalInOut
#spi = board.SPI()
#bme_cs = digitalio.DigitalInOut(board.D10)
#bme280 = adafruit_bme280.Adafruit_BME280_SPI(spi, bme_cs)

# change this to match the location's pressure (hPa) at sea level
bme280.sea_level_pressure = 1013.25

while True:
    print("\nTemperature: %0.1f C" % bme280.temperature)
    print("Humidity: %0.1f %%" % bme280.relative_humidity)
    print("Pressure: %0.1f hPa" % bme280.pressure)
    print("Altitude = %0.2f meters" % bme280.altitude)
    time.sleep(2)
