LDRobot DTOF Laser Ranging Sensor, 360° Omni-Directional Lidar, UART Bus

The laser ranging core, angle measurement unit, motor driving unit, wireless transmission unit, wireless communication unit, and mechanical housing make up the majority of LD19. Using DTOF technology, the LD19 ranging core takes measurements 4500 times per second. In order for LD19 to function, an infrared laser must be pointed forward. Once it reaches the target object, the laser is reflected back to the single photon receiving device. As a result, we obtain the laser’s emitting and receiving times, with the travel time occurring in between. We are able to compute the distance using the speed of light. Upon obtaining the distance data, LD19 will merge it with the angle value obtained from the angle measuring device to create the points cloud data to an external interface via wireless communication. Meanwhile, the external interface provides PWM to allow the motor driving unit to drive the motor. After the external control unit gets the rotational speed, it will reach to specified speed through PID algorithm closed-loop control to ensure LD19 works stably.
