[^3]: The exact ranges and angles, in which a specific target is detected, is dependent on target reflectivity and can be adapted by selecting different sensor parameters.<br>Sensor parameters used for testing: number of pulses = 8, echo rejection = 1, peak detection window = 1, 36 cm x 36 cm cardboard target

[^4]: Typical values are derived from tests under controlled conditions in an indoor environment with a standardized target (aluminium pole, diameter: 75 mm) at 1m distance. Actual values may vary due to environment conditions (e.g. airflow, temperature, humidity) and target reflectivity.<br>Sensor parameters used for testing: number of pulses = 5, echo rejection threshold = 3, peak detection window = 1
[^5]: Smallest difference in range between two targets for the sensor to be able to separate them into two signals / points. Targets in a smaller distance to each other can result in a merging signal returning a non-truthful angle measurement.
