In order to protect ultrasonic sensors from interference and ensure that their measurements are stable and reliable, the following measures can be taken:
1. Avoid co-frequency interference
· When multiple sensors work at the same time, use different working frequencies or polling trigger methods to prevent signal confusion.
· Products with anti-interference algorithms or synchronization functions are preferred.
2. Avoid strong noise sources
· Stay away from strong noise equipment (such as pneumatic valves, high-speed motors), or add sound insulation/shock-absorbing materials.
· Avoid installation directly facing high-noise reflective surfaces.
3. Optimize installation position
· The sensor is installed facing the target to reduce angle errors and oblique reflections.
· Keep the sensor transmitting surface clean and avoid dust and water droplets.
4. Avoid temperature fluctuations and airflow interference
· Avoid the sensor facing strong airflow areas such as air conditioners and heaters.
· Choose sensors with temperature compensation function to reduce the impact of ambient temperature on measurement accuracy.
5. Electrical interference protection
· Use shielded cables to ensure good grounding and avoid electromagnetic interference.
· Avoid parallel wiring of sensors and high-current cables.
Through the above methods, the stability and reliability of ultrasonic sensors in complex environments can be effectively improved. If there are high-interference application scenarios, industrial-grade ultrasonic sensors with enhanced anti-interference functions can be selected.
