LD06 is mainly composed of laser ranging core, wireless transmission unit, wireless communication unit, angle measurement unit, motor drive unit and mechanical casing. The LD06 ranging core uses DTOF technology and measures 4500 times per second. When working, LD06 emits infrared laser forward. When the laser encounters the target object, it is reflected to the single-photon receiving unit. In this way, we get the time of laser emission and reception, and the difference between them is the flight time. With the speed of light, we can calculate distance. After LD06 receives the distance data, it combines it with the angle value obtained by the angle measurement unit to form point cloud data, and then transmits the point cloud data to the external interface through wireless communication. At the same time, the external interface provides PWM to allow the motor drive unit to drive the motor. After the external control unit obtains the rotational speed, it reaches the specified rotational speed through the closed-loop PID algorithm. 12m measurement radius 30000lux anti-glare 4500HZ measurement frequency 360 scanning range laser safety (TOF) time-of-flight ranging Small size, simple operation and installation 10000h service life
