The first step is to create a new Adafruit IO feed to hold the AD7410's temperature. Navigate to the [feeds page](https://io.adafruit.com/feeds) on Adafruit IO. Then click **Actions -\> Create New Feed** , and name this feed **temperature**.  - If you do not already know how to create a feed, head over to [Adafruit IO Basics: Feeds](https://learn.adafruit.com/adafruit-io-basics-feeds). ![](https://cdn-learn.adafruit.com/assets/assets/000/071/021/medium800/weather_tmp_Feed.png?1549906906) ## Dashboard Setup  Next, step is to create a dashboard to display the value read by the ADT7410 sensor. - If you do not know how to create or use Dashboards in Adafruit IO, head over to the [Adafruit IO Basics: Dashboards](https://learn.adafruit.com/adafruit-io-basics-dashboards) guide. **Select the Gauge block. ** ![weather_IO_-_Feather_Huzzah___ADT7410_Gauge.png](https://cdn-learn.adafruit.com/assets/assets/000/070/951/medium640/weather_IO_-_Feather_Huzzah___ADT7410_Gauge.png?1549640799) **Select the _temperature_ feed**  created earlier. ![weather_temperature.png](https://cdn-learn.adafruit.com/assets/assets/000/071/022/medium640/weather_temperature.png?1549906963) In the Block Settings step,  **set the Block Title to Temperature** , **set the Gauge Min/Max Values to the upper and lower temperature thresholds**  you want to measure. You can label the gauge by setting the Gauge Label - this example assumes temperature is to be measured in Degrees C. _Uncomfortably hot/cold? _You can optionally set the gauge change color to warn you if the temperature goes above (or below) a certain value. ![weather_IO_-_Feather_Huzzah___ADT7410.png](https://cdn-learn.adafruit.com/assets/assets/000/070/949/medium640/weather_IO_-_Feather_Huzzah___ADT7410.png?1549640961) After adding the gauge element, your dashboard will look like the following: ![](https://cdn-learn.adafruit.com/assets/assets/000/070/950/medium800/weather_IO_-_Feather_Huzzah___ADT7410_dash.png?1549640507) 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 later. ![](https://cdn-learn.adafruit.com/assets/assets/000/070/894/medium800thumb/weather_3d_printing_adafruit_io_username_and_password.jpg?1549578887) # IoT Temperature Logger with Analog Devices ADT7410, Raspberry Pi, and Adafruit IO ## Wiring Need a way to connect your Raspberry Pi to a breadboard?

To install it, **enter the following into the terminal on your Raspberry Pi** : `sudo apt-get install ttf-mscorefonts-installer` ## Installing CircuitPython Libraries Since CircuitPython is running on the Raspberry Pi - installing the libraries for this guide is quick and easy. To [**install the library for the display**](https://github.com/adafruit/Adafruit_CircuitPython_SSD1306),  **enter the following into the terminal** **`sudo pip3 install adafruit-circuitpython-ssd1306`** You'll also need to [install the CircuitPython library to read data from the Analog Devices ADT7410](https://github.com/adafruit/Adafruit_CircuitPython_ADT7410):  **`sudo pip3 install adafruit-circuitpython-adt7410`** The code for this project is below. **Save it to the Raspberry Pi** as **`adafruit_io_adt7410.py`** https://github.com/adafruit/Adafruit_Learning_System_Guides/blob/main/adafruitio-adt7410/adafruit_io_adt7410.py Before running the code, you'll need to **set the `ADAFRUIT_IO_KEY` to the Adafruit IO Key** we saved earlier and **set the `ADAFRUIT_IO_USERNAME` to your Adafruit IO Username**. When both of these variables are changed, save the file. You can **run the program by entering the following in your terminal** : **`python adafruit_io_adt7410.py`** **and Press the Enter Key**. You should see the following print out in your terminal ``` Sending temperature 22.26 C to Adafruit IO Sending temperature 22.27 C to Adafruit IO Sending temperature 22.25 C to Adafruit IO Sending temperature 22.27 C to Adafruit IO Sending temperature 22.28 C to Adafruit IO ``` The display should display the temperature read from the ADT7410 along with the status of the data being sent to Adafruit IO. ![raspberry_pi_ezgif.com-video-to-gif_(2).gif](https://cdn-learn.adafruit.com/assets/assets/000/071/027/medium640thumb/raspberry_pi_ezgif.com-video-to-gif_%282%29.jpg?1549912793) Next, we're going to check that the data has been received by Adafruit IO. We can do this [by visiting the Adafruit IO Monitor page](https://io.adafruit.com/monitor). Every 30 seconds, the page will refresh with the latest values from the ADT7410.   If you want to change the delay, change the variable `DELAY_SECONDS` to the desired delay between sensor reads.  ![raspberry_pi_live_feed.png](https://cdn-learn.adafruit.com/assets/assets/000/071/023/medium640/raspberry_pi_live_feed.png?1549913257) Navigate to the dashboard you created earlier to view the temperature gauge we added. Every 30 seconds, it'll update and display a new value. ![raspberry_pi_adi_dash.png](https://cdn-learn.adafruit.com/assets/assets/000/071/026/medium640/raspberry_pi_adi_dash.png?1549911616) For more information about the ADT7410 CircuitPython library, [check out the latest docs!](https://circuitpython.readthedocs.io/projects/adt7410/en/latest/) ## Featured Products ### Raspberry Pi 3 - Model B+ - 1.4GHz Cortex-A53 with 1GB RAM [Raspberry Pi 3 - Model B+ - 1.4GHz Cortex-A53 with 1GB RAM](https://www.adafruit.com/product/3775) The Raspberry Pi 3 Model B is the most popular Raspberry Pi computer made, and the Pi Foundation knows you can always make a good thing _better_!
