Publish data to the Internet of Things using ThingSpeak
Simulink Support Package for Android Devices / Communication
You can publish data from your target hardware to the Internet of Things using ThingSpeak.
ThinkSpeak is a web service for Internet of Things applications. It provides real-time data collection, data processing, visualizations, apps, and plugins.
For more information on how to use ThingSpeak, see Apps, Plugins, or Tutorials.
Get the Channel ID parameter from your channel in ThingSpeak.com.
After creating a ThingSpeak channel for your target hardware:
In the ThingSpeak.com website, select Channels > My Channels.
Under the channel that you created for this target hardware, click Settings.
Click the Channel Settings tab and copy the Channel ID.
Open the ThingSpeak Write block in your model and paste the value into the Channel ID parameter.
Get the Write API Key parameter from your channel in ThingSpeak.com.
After creating a ThingSpeak channel for your target hardware:
In the ThingSpeak.com website, select Channels > My Channels.
Under the channel that you created for this target hardware, click Settings.
Click the API Keys tab.
Copy the key from Write API Key parameter.
Open the ThingSpeak Write block in your model and paste the API key into Write API key parameter.
Set the number of fields to send.
The default value is 1
.
Set the number of seconds to wait between sending the data.
The default value is 60
seconds.
When this parameter is set to:
Input port
, specify the location
using a signal that is connected to the location block
input.
Block dialog
, specify the location
using the Location (latitude, longitude, altitude) parameter.
In both cases, specify the location as a cell array of three elements:
[latitude
,longitude
,altitude
]
Use decimal degrees notation to specify latitude and longitude. Use meters to specify altitude. For example:
The lowest human-sized point underground, the TauTona
Mine in Carletonville, South Africa: [-26.416111,27.4275,-3900]
The highest point measured from sea level, the summit
of Mount Everest in Nepal: [27.988056,86.925278,8848]
Setting the Send location information parameter
to Block dialog
displays this parameter.
Specify the location as a cell array of three elements:
