HY-SRF05 Precision Ultrasonic Sensor
An ultrasonic ranging sensor with slightly better accuracy.
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. THIS particular model is an upgrade from the lower precision HC-SRO4. This has 5 pins and can be used in 1pin trigger/echo or 2-pin. The SRF05 UltraSonic range finder lets you find the distance of the objects in front of it. It does that by sending ultrasonic pulses and measures the time it takes for the pulses to travel to the obstacle and back.
