​Usually, this usage method involves fixing the equipment on a gantry on a highway or core road, with the laser transmitter and receiver facing vertically towards the ground and aligned with the center of the lane. When a vehicle is driving, the distance sensor can output the relative change value of the measured distance value in real time, thus depicting the outline of the motor vehicle.

​With the development of space technology and aerospace industry. Space distance measurement has become an important research topic in the field of space. Traditional radar ranging is highly susceptible to interference from high-energy particles and electromagnetic waves in space, resulting in low measurement accuracy and inability to meet the requirements of high-precision measurement. The air in space is thin and the temperature changes dramatically, making it impossible to perform ultrasonic ranging. Therefore.

The infrared range finder has the advantages of high automation, fast ranging speed and high accuracy. However, if the instrument is improperly used or poorly maintained, the performance of the early instrument may change, resulting in a reduction in accuracy.

At present, Nissan Motor Corporation has successfully developed an automatic pedestrian avoidance system. The system is composed of a camera and five laser ranging sensors, which can sense obstacles within the range of 20 meters on the left and right sides of the vehicle, 150 meters in front of the vehicle and 70 meters behind the vehicle. Once a pedestrian suddenly appears in front of the vehicle, the system automatically controls the steering wheel and takes avoidance actions, which can not only avoid pedestrians, but also avoid collision with other vehicles. At present, the automatic brake * * system has been developed and loaded on some vehicles. The steering wheel control system developed this time can solve the traffic accidents that cannot be prevented by braking, and the technology is advanced.

Laser measurement sensors are often used in industry and research to verify dimensions of length, width, or thickness. Typical applications include determining wood thickness, steel coil thickness, paper coil width, and so on. The reason why engineers choose non-contact laser sensors is that they are very accurate, fast, and the distance between the measuring device and the surface of the measured object can be very far.

​Sensors are like the eyes, ears, mouth, and nose of humans, but they are not just about human senses. They can even collect more useful information. In that case, it can be said that these sensors are the foundation of the entire IoT system, and it is precisely because of sensors that the IoT system has content transmitted to the "brain".
