HY-SRF05 Ultrasonic Distance Measuring Transducer Sensor Module for Dev boards

High 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 obstacles are not missed by a narrow sensor beam. High quality at affordable prices! Select your package, 3 units or 5 units.
