The newest CooCoo ultrasonic sensor of ALSRobot adopts the dual-probe design and is equipped with a high-precisionprocessing chip, which greatly improves the detection distance and precision. The detection distance can be up to 300cm and the precision can be up to 1cm.It can be calibrated automatically within the effective detection range, and the accurate distance of obstacle can be obtained without any manual adjustment.Make your robot feel its surroundings through sonar like a bat.You only need to write a short program in the single-chip computer and CooCoo controller to control the motor operation of the robot according to the distance of obstacles, so that your robot can easily avoid obstacles and realize its function of detection and obstacle avoidance.
