Cloud Data Logging with Raspberry Pi

is a credit-card-sized single-board computer. Because it is low-cost and easy to equip with various types of sensors, using Raspberry Pi as a cloud data logger is one of its ideal use cases.

This article introduces how to transport sensor data from Raspberry Pi to the cloud, using Fluentd as the data collector. For the cloud side, we'll use the cloud data service as an example, but you can use any cloud service in its place.

Install Raspbian

Install Fluentd

Next, we'll install Fluentd on Raspbian. Raspbian Stretch with desktop and recommended software bundles Ruby 2.3.3 by default, but we need the extra development package to install Fluentd:

$ sudo aptitude install ruby-dev

We'll now install Fluentd and the necessary plugins:

$ sudo gem install fluentd
$ sudo fluent-gem install fluent-plugin-td

Configure and Launch Fluentd

Please prepare the fluentd.conf file with the following information, including your API key:

<match td.*.*>
  @type tdlog
  apikey YOUR_API_KEY_HERE

  auto_create_table
  <buffer>
    @type file
    path /home/pi/fluentd/td
  </buffer>
</match>

<source>
  @type http
  port 8888
</source>

<source>
  @type forward
</source>

Finally, please launch Fluentd via your terminal:

$ fluentd -c fluent.conf

Upload Test

To test the configuration, just post a JSON message to Fluentd via HTTP:

$ curl -X POST -d 'json={"sensor1":3123.13,"sensor2":321.3}' \
  http://localhost:8888/td.testdb.raspberrypi

Now, access the databases page to confirm that your data has been uploaded to the cloud properly.

You can now issue queries against the imported data.

For example, these queries calculate the average sensor1 value and the sum of sensor2 values:

SELECT AVG(sensor1) FROM raspberrypi;
SELECT SUM(sensor2) FROM raspberrypi;

Conclusion

Raspberry Pi is an ideal platform for prototyping data logger hardware. Fluentd helps Raspberry Pi transfer the collected data to the cloud easily and reliably.

is a free operating system based on Debian, optimized for the Raspberry Pi. Please install Raspbian on your Raspberry Pi by following the instructions in the blog post below:

Please sign up to Treasure Data from the . Its free plan lets you store and analyze millions of data points. You can get your account's API key from the .

NOTE: If you're using Python, you can use Fluentd's library.
