3. Sensors

To view the sensor gallery, click on the Sensors tab.

All available sensors are listed here, with the ability to page through the list and perform queries on the available sensors, filter based on tags, organizations and visibility.

From there, there are three additional list views:

  • All Available: display all of the sensors you can view on the WoTKit including public sensors, sensors that are in organizations you are a member of, and any private sensors you’ve contributed.
  • Subscribed: showing all sensors to which the user has subscribed.
  • Contributed: showing all sensors the user has added to the WoTKit.

These list views can be further narrowed as follows: * Using the search bar at the top of the screen. This searches by text contained in the sensor name and description.

  • Selecting a tag from the tag list displayed on the left of the screen.
  • Selecting the Show Active button displayed on the left of the screen. Active sensors are those which have received data in the last 15 minutes.

In addition to this list view, a map view is available that is automatically centered on the sensors in your list view.
