direktionssensor

A direktionssensor, also known as a directional sensor, is a type of sensor designed to detect the direction of a phenomenon. Unlike omnidirectional sensors that register a stimulus regardless of its origin, direktionsensors provide information about the source's location or orientation relative to the sensor.

These sensors are employed in a wide range of applications. In robotics and autonomous systems, they are crucial for navigation and obstacle avoidance, helping vehicles understand where other objects are located. In environmental monitoring, they can pinpoint the source of pollution or seismic activity. In astronomy, specialized direktionsensors are used to track celestial bodies.

The underlying technology of a direktionssensor can vary greatly depending on the type of phenomenon being detected. For light, this might involve using multiple photodiodes or a single photodiode with a physical shading mechanism. For sound, directional microphones often employ an array of sensing elements or acoustic baffles. Magnetic field direction can be sensed using multiple Hall effect sensors or specialized magnetometers.

The output of a direktionssensor typically indicates the angle or vector of the detected phenomenon. This information is then processed by a control system or used for data analysis. The accuracy and resolution of a direktionssensor are key performance parameters, determining its suitability for specific tasks.
