HY-SRF05 5Pin Ultrasonic Distance Sensor




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 gaurantee that obstacles are not missed by a narrow sensor beam.
