Ultrasonic Distance Sensor (HY-SRF05)

Interfacing to a microcontroller is a snap. After a trigger impulse an ultrasonic burst (well above human hearing) is produced and then "listen" for the echo return pulse. The sensor measures the time required for the echo return, and returns this value to the microcontroller as a variable-width pulse.

Key Features

• Provides precise, non-contact distance measurements to 4 m range
• Ultrasonic measurements work in any lighting condition, making this a good choice to supplement infrared object detectors
• 5-pin header makes it easy to connect to a development board, directly or with an extension cable, no soldering required

Application Ideas

• Security systems
• Interactive animated exhibits
• Parking assistant systems
• Robotic navigation
