isSensorOf

isSensorOf is a binary relation used in modeling, software design, and knowledge representations to express that one entity functions as a sensor for another entity or target. In this relation, the first argument is the sensor and the second is the subject being observed or monitored, such as a device, environment, or subsystem.

Formal representations of isSensorOf vary by context. In a knowledge graph or data model, it can be written as isSensorOf(sensor, target). In code, it may appear as a boolean function or a property, for example sensor.isSensorOf(target) or sensor.target == target. The relation is typically observational and does not imply control or action by the sensor.

Semantics and usage. A sensor collects data about its target or the surrounding environment, and the relation may connect to data types, units, timestamps, and accuracy metrics. A sensor can observe multiple targets, and a single target can be observed by multiple sensors. The concept helps distinguish sensing from other roles such as actuating or processing data.

Examples. A temperatureSensor isSensorOf(roomA); a moistureSensor isSensorOf greenhouseSector1; a camera sensor isSensorOf corridorZ. In simulations, isSensorOf can link virtual sensors to simulated entities to enable data fusion and event generation.

Applications and considerations. isSensorOf is common in IoT networks, robotics, and simulation environments to organize sensing topology, support data fusion, and enable event-driven processing. When using the relation, it is useful to specify data characteristics (type, range, accuracy) and establish whether sensors are ambient, intrusive, or targeted.
