Range Finder low cost distance measurement device

If you are looking for Range Finder, to measure the distance then here is Parallax's PING)))™ ultrasonic sensor, which is perfect for varies applications that require you to perform measurements between moving or stationary objects.

Applicable in:

•    Robotics
•    Security systems or as an infrared replacement


  • Through sonar Ping sensor measures distance

  • An ultrasonic (above human hearing) pulse is transmitted from the unit and distance-to-target is determined by measuring the time required for the echo return.

  • Output from the PING))) sensor is a variable-width pulse that corresponds to the distance to the target.


  • Provides precise, non-contact distance measurements within a 2 cm to 3 m range

  • Simple pulse in/pulse out communication

  • Burst indicator LED shows measurement in progress

  • 20 mA power cosumption

  • Narrow acceptance angle

  • 3-pin header makes it easy to connect using a servo extension cable, no soldering required

Key Specifications:

  • Power requirements: +5 VDC

  • Communication:Positive TTL pulse

  • Dimensions: 0.81 x 1.8 x 0.6 in (22 x 46 x 16 mm)

  • Operating temp range: +32 to +158 °F (0 to +70 °C)
