Sensordependent

Sensordependent is an adjective used to describe a system, device, or process that relies on data from one or more sensors to function or make decisions. In a sensordependent design, sensor measurements determine state, control actions, or outputs, rather than predetermined or fixed rules. The term underscores the dependency on sensor accuracy, calibration, and timely data, and implies that sensor failure or degraded measurements can affect performance.

Applications span many fields, including robotics, mobile computing, the Internet of Things, and industrial automation. Examples include smartphones that adjust screen orientation based on accelerometer data, autonomous vehicles that fuse lidar, radar, and camera inputs to navigate, and agricultural systems that optimize irrigation using soil moisture and weather sensors. Sensordependent approaches also appear in health monitoring devices that track vital signs to infer activity or risk.

Design and operation present challenges such as sensor noise, drift, and calibration needs, as well as data latency and power consumption. Effective sensordependent systems often employ data fusion, filtering (for example, Kalman or complementary filters), fault detection, and redundancy to maintain reliability. Privacy and security concerns arise when sensor data captures sensitive information or environmental context.

People may refer to sensordependent systems as sensor-driven or sensor-based, reflecting the central role of sensing in their behavior. When sensor data is unavailable, such systems may switch to safe modes, degrade gracefully, or rely on fallback rules.
