    Tips: Laser sensors vs. ultrasonic sensors
    Ultrasonic sensors are also often used to detect objects at greater distances, and since it is not an optical device, it is not affected by color changes. However, ultrasonic sensors measure distance based on the speed of sound, so they have some inherent disadvantages and cannot be used in the following situations.

    1. When the target to be measured is not perpendicular to the transducer of the sensor. The target of ultrasonic detection must be within an angle of no more than 10° from the vertical azimuth of the sensor.
    2. When the beam diameter is small. The general ultrasonic beam is 0.76cm in diameter when it is 2m away from the sensor.
    3. When a visible spot is required for position calibration.
    4. Windy occasions.
    5. Vacuum occasions.
    6. When the temperature gradient is large. In this case the speed of sound will change.
    7. Occasions that require quick response.

    While the laser sensor can solve the detection of all the above occasions, which cannot be done by ultrasonic sensors.

    300mm/50m laser sensor suitable for my use
    This 300mm/50m laser sensor is much better than I expected. It has a variety of measurement modes and easy-to-use controls, making it ideal for professionals like me.
