Software

• Raspbian
• Python 3
• Python Library: smbus2
• Python Library: RPi.bme280
• AmbientDataInc/ambient-python-lib

Usage

Send Temperature Humidity and Pressure to Ambient

$ cd ~/ambient_device
(py36) $ python ambient_device.py

Example installation in pyenv environment

1. Clone this project

    $ cd ~
    $ git clone https://github.com/KeitetsuWorks/ambient_device.git
    $ cd ambient_device
   

2. Install dependent libraries

    $ pyenv virtualenv 3.6.6 py36
    (py36) $ pyenv local py36
    (py36) $ pip install smbus2
    (py36) $ pip install RPi.bme280
    (py36) $ pip install git+https://github.com/AmbientDataInc/ambient-python-lib.git
   

3. Make the configuration file, ambient.json

    (py36) $ vi ambient.json

    {
        "ambient": {
            "channelId": "your_channel_id",
            "writeKey": "your_write_key"
        }
    }
   

4. (Optional) Edit cron for periodic execution

    $ crontab -e
   

   ambient_device.sh is shell script to run ambient_device.py using pyenv environment from crond.
