What should you pay attention to when using ultrasonic sensors in outdoor environments?

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.

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.

Impact: Water droplets may adhere to the surface of the probe or interfere with the propagation of sound waves.

Recommendation:

· Clean the sensor surface regularly;

· Appropriately install a rain cover or shell.

Impact: High temperature may cause aging of electronic components or increase errors.

Recommendation: Avoid direct sunlight, or install a sunshade for protection.

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.

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.

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.
