IoT Permafrost Monitor

To visualize charts the App uses two methods you can choose from - ThingSpeak™ chart web API or MPAndroidChart library. The first one is used by default. Unfortunately it does not support zooming and only one chart can be shown at once. MPAndroidChart library allows to build multiple charts on single screen and supports zooming.

The channel ID and the API key is needed to open private channel.

To visualize public ThingSpeak™ channel the App automatically embeds widgets from ThingSpeak™ website. It can be chart, gauge or any other type of widget including MATLAB Visualizations that is shown on a public page of the channel.

Unnecessary widgets can be hidden for any channel type.

Any chart can be opened on a separate screen in details. Its options can be changed and stored locally including charts that are opened from homescreen widgets. This will not affect data stored on ThingSpeak™ server.

Any widget can be opened on a separate screen.

Homescreen widget is very useful part of the App that helps to view channel fields data without launching an application. One homescreen widget can visualize up to 8 fields from different channels showing a gauge, lamp indicator, compass or numeric value. Each field can send notification when value threshold exceeded. To fit into homescreen widget space the field name can be changed locally.
