Sensorauflösung

Sensorauflösung refers to the smallest change in a physical quantity that a sensor can detect and reliably report. It is a fundamental characteristic that defines the precision of a sensor. A higher sensor resolution means the sensor can distinguish between finer increments of the measured parameter, leading to more detailed and accurate measurements. Conversely, a lower resolution sensor will average out small variations, potentially missing important details.

The resolution of a sensor is often expressed in the same units as the physical quantity it measures. For example, a temperature sensor might have a resolution of 0.1 degrees Celsius, meaning it can detect changes as small as one-tenth of a degree. In digital sensors, resolution is also influenced by the number of bits used in the analog-to-digital converter (ADC). A higher bit depth allows for a greater number of discrete levels to represent the analog signal, thus increasing the potential resolution. However, the actual resolution is also limited by other factors such as noise within the sensor and the electronics, as well as the inherent precision of the physical sensing element itself. Understanding sensor resolution is crucial for selecting the appropriate sensor for a given application, ensuring that the required level of detail in measurements can be achieved.
