+The air sensor sample data is designed to represent an "Internet of Things" (IoT) use case
+ by simulating temperature, humidity, and carbon monoxide levels for multiple rooms in a building.
+The dataset also includes a relational SQL dataset with meta information about sensors in each room.

+This sample data is adapted from the [Movebank: Animal Tracking](https://www.kaggle.com/pulkit8595/movebank-animal-tracking)
+dataset available on [kaggle.com](https://kaggle.com).
+The dataset as a whole represents animal migratory movements throughout 2019.
+The data schema meets the requirements of the
+[Flux Geo package](https://v2.docs.influxdata.com/v2.0/reference/flux/stdlib/experimental/geo/#geo-schema-requirements)
+which contains tools for working with geo-temporal data.
