Customize IoT Central

In this exercise, you will be customizing Azure IoT Central to display the data sent from the applications you run on the Altair emulator. Applications that stream data to Azure IoT Central include WEATHER.BAS and JSON.BAS.

Open the Azure IoT Central device explorer​

  1. Go to Azure IoT Central.

  2. On the left pane, select Devices select your device.

    It might take a minute or two for the Altair emulator device to register in the devices section of Azure IoT Central.

Customize the Climate monitor template​

The Altair emulator supports IoT Plug and Play. When the Altair emulator connects to Azure IoT Central, the Climate Monitor Plug and Play model is loaded from the public repository of models. Default views are created for the Climate Monitor model. These default views are a great starting point, but they need customization along with some new views.

The IoT Plug and Play model is declared in the main.h file.

#define IOT_PLUG_AND_PLAY_MODEL_ID "dtmi:com:example:climatemonitor;2"

    9. Wind speed

Notes. Pollutants produced by vehicle exhausts include carbon monoxide, hydrocarbons, nitrogen oxides, particles, volatile organic compounds, and sulfur dioxide. Hydrocarbons and nitrogen oxides react with sunlight and warm temperatures to form ground-level ozone. Ground-level ozone, a key ingredient in smog, can cause upper respiratory problems and lung damage.
