A：
1. Ambient temperature fluctuations
Impact: Temperature will change the speed of sound, which will affect the ranging accuracy.
Recommendation: Choose a sensor with temperature compensation function, or add an external temperature sensor for correction.
2. Strong wind interference
Impact: Wind will disrupt the ultrasonic propagation path, resulting in unstable measurement.
Recommendation: Try to install in a windproof area, or use a sensor with windproof design.
3. Rain, snow and humid environment
Impact: Water droplets may adhere to the surface of the probe or interfere with the propagation of sound waves.
Recommendation:
· Use equipment with IP65 or higher protection level;
· Clean the sensor surface regularly;
· Appropriately install a rain cover or shell.
4. Direct sunlight
Impact: High temperature may cause aging of electronic components or increase errors.
Recommendation: Avoid direct sunlight, or install a sunshade for protection.
5. Dust and insect interference
Impact: May adhere to the surface of the transducer, reducing sensitivity.
Recommendations:
· Perform regular maintenance and cleaning;
· Choose products with self-cleaning coating or anti-pollution design.
6. Target object characteristics
Influence: Soft materials or inclined surfaces may reflect poorly.
Recommendations: Confirm that the target surface has a good reflection effect on sound waves, or adjust the installation angle.
7. Installation firmness and position
Recommendations:
· The sensor should be firmly installed to avoid vibration;
· The installation angle should be perpendicular to the object to be measured to avoid reflection offset;
· Keep the transmitting surface unobstructed.
