HY-SRF05 Ultrasonic Distance Measuring Transducer Sensor Module for Dev boards Qty:5 units New L298N DC Stepper MotorHigh Precision Ultrasonic Distance Sensor, HY SRF05 High Precision, the new generation! This model is an upgrade from the lower precision HC SR04. This has 5 pins and can be used in 1 pin trigger echo or 2 pin. Ultrasonic sensors overcome many of the weaknesses of IR sensors they provide distance measurement regardless of color and lighting of obstacles. They also provide lower minimum distances and wider angles of detection to guarantee that
