A sensor mechanism in an environmental monitoring device provides sensor data that represents an environmental condition in an external environment that includes the environmental monitoring device. Then, a control mechanism in the environmental monitoring device generates subsets of the sensor data based on data privileges of different entities, where the data privileges of at least some of the entities are different from each other, and at least some of the corresponding subsets of the sensor data are different. For example, the data privileges may specify: different spatial extents in the external environment monitored by the sensor mechanism; and/or different types of information associated with the external environment. Next, an interface circuit in the environmental monitoring device provides the subsets of the sensor data to electronic devices associated with the entities.
