Getting Started

As good first task we'll walk you through building a simple temperature sensing network. It can be built quickly and easily with minimal knowledge of programming or Microsoft Azure, using commodity devices available locally or online - for example an Arduino UNO board with a weather shield, connected to a Raspberry Pi sending data to an Azure website.

Sample code for this is included in the project.

Hardware prerequisites for Connect The Dots getting started project

If you are going to deploy the starter solution, you need to procure an Arduino UNO and Raspberry Pi, as shown in the documentation for those devices in the appropriate folders:

  • [Arduino UNO R3 and weather shield](Devices/GatewayConnectedDevices/Arduino UNO/Weather/WeatherShieldJson/
  • Raspberry Pi

Software prerequisites

In order to reproduce one of the scenarios, you will need the following:

  1. Microsoft Azure subscription (free trial subscription is sufficient)
  2. [optional] Visual Studio 2013 or above – Community Edition is sufficient. Note that if you are not planning to use the Gateway nor making changes to the dashboard, you will NOT need Visual Studio.
  3. [optional] WiX Toolset - if you want to build installer of Gateway for Windows

Setup Tasks

Setting up your IoT solution involves several distinct steps, each of which is fully described in this project:

  1. Clone or copy the project to your machine (NOTE: place the project in a folder as close to the root of your file system as possible. Some paths in the project are very long and you might encounter issues with long path names when restoring NuGet packages)
  2. Deploy Azure services - Creating Azure resources
  3. Device setup - Configuring your device(s)

To get started with our simple example, complete the tasks above in order. Navigation is provided on each page to get to the next topic.

Run the scenario

Once you have setup the services, published the site, provisioned and connected your devices, you will see data coming up on your website at the URL you chose when deploying the site.

You should see average temperature measurements showing up in the web browser every 20 seconds.

If you select “All”, you should see raw readings from the device coming in every second. If the temperature exceeds 80 degrees (F), you should see an alert showing in the alerts table, once every 20 seconds while the temperature on any of the devices exceeds 80 degrees (F). If you cover the shield, you will see an alert telling you the light is turned off.
