Adafruit IO is a platform designed by Adafruit to display, respond, and interact with your project's data. Adafruit keeps your data private (data feeds are private by default) and secure (we will never sell or give this data away to another company) for you. It's the internet of things - for everyone!
If you do not already have an Adafruit IO account set up, head over to io.adafruit.com to link your Adafruit.com account to Adafruit IO.
Feeds are the core of the Adafruit IO system. The feed holds metadata about the data you push to Adafruit IO. We'll be creating two feeds - temperature and moisture.
Change the feed name to Temperature. We may also optionally add a description here. Click Create to create a new feed.
Then, create another feed called moisture.
Next, we'll create a dashboard to display the values from the feeds we created.
- For a primer about Adafruit IO Dashboards, head over to the Adafruit IO Basics: Dashboards guide.
The STEMMA Soil Sensor provides a soil moisture reading from very dry to very wet along with an ambient temperature reading from the internal temperature sensor on the microcontroller.
From the dashboard, click the + button to create a new block.
From the modal, Click the Line Chart block.
The line chart can graph one or more feeds.
The line chart can graph one or more feeds. We'll be graphing the moisture and temperature feed values to see how they change over time.
Search for the temperature feed. Click the checkbox. Then, search for the moisture feed. Click the checkbox.
Click Next Step
Name the Block Title as Temperature and Moisture
Set Show History to 4 hours
A gauge is a read only block type that shows a fixed range of values. We'll add two gauge blocks to the dashboard to display values from the planter in real-time.
From the feed list, select the moisture feed.
Set Block Title to Moisture.
The moisture sensor can read values up to 2000, set Gauge Max Value to 2000.
Tick the Show Icon button and set the icon to w:raindrop.
Let's make another gauge block to display the temperature sensor's value.
Click Create a new block.
Set the Block Title to Temperature.
Set the Gauge Label to F
We can optionally set the Low Warning Value or High Warning Value. The gauge will change color when the value is out of bounds.
Tick the Show Icon button and set the icon to w:thermometer.
If your account has an active Adafruit IO Plus subscription, you can optionally add a header image to customize your dashboard.
Download the image by clicking the button below and save it somewhere safe on your computer.
Click the Edit Dashboard Layout (Green Gear) button.
Next to the dashboard's title, click Edit Settings.
Under Header Image, select the image you downloaded in the previous step.
Tick the checkbox next to Show Header Image
Your dashboard should look like the screenshot below.
You are also going to need your Adafruit IO username and secret API key.
Navigate to your profile and click the View AIO Key button to retrieve them. Write them down in a safe place, you'll need them for the next step.
Now that we've set up our Adafruit IO account, let's move on to setting up the PyPortal Titano.
