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

A： 1. Ambient temperature fluctuations Impact: Temperature will change the speed of sound, which will affect the ranging accuracy. 2. Strong wind interference Impact: Wind will disrupt the ultrasonic propagation path, resulting in unstable measurement. 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. 4. Direct sunlight Impact: High temperature may cause aging of electronic components or increase errors. 5. Dust and insect interference Impact: May adhere to the surface of the transducer, reducing sensitivity. 6. Target object characteristics Impact: Soft materials or inclined surfaces may reflect poorly. 7. Installation firmness and position
