How do ultrasonic sensors handle measurements on irregular or tilted surfaces?

Ultrasonic sensors measure distance by emitting and receiving sound waves, but for irregular or inclined surfaces, the echo signal may be weakened or the reflection may deviate. To improve measurement accuracy, the following methods are usually used:

1. Choose a suitable installation angle: Aim the sensor at the possible reflection direction of the target to avoid signal deviation caused by too large an angle.

2. Use wide beam or multi-sensor configuration: Improve coverage and echo capture rate.

3. Use intelligent filtering and signal processing algorithms: Enhance the ability to suppress clutter and identify true echoes.

4. Set appropriate detection thresholds and delay times: Avoid false triggering or missed detection.

By optimizing installation and settings, ultrasonic sensors can more reliably measure the distance of objects on irregular or inclined surfaces.
