Parallax PING))) 28015 User Manual

PING))) Ultrasonic Distance Sensor (#28015)
The Parallax PING)))™ ultrasonic distance sensor provides precise, non-contact distance measurements
from about 2 cm (0.8 inches) to 3 meters (3.3 yards). It is very easy to connect to microcontrollers such
®
as the BASIC Stamp , Propeller chip, or Arduino, requiring only one I/O pin.
The PING))) sensor works by transmitting an ultrasonic (well above human hearing range) burst and
providing an output pulse that corresponds to the time required for the burst echo to return to the
sensor. By measuring the echo pulse width, the distance to target can easily be calculated.
Features

Range: 2 cm to 3 m (0.8 in to 3.3 yd)

Burst indicator LED shows sensor
activity

Bidirectional TTL pulse interface on a
single I/O pin can communicate with 5 V
TTL or 3.3 V CMOS microcontrollers

Input trigger: positive TTL pulse, 2 µs
min, 5 µs typ.

Echo pulse: positive TTL pulse, 115 µs

Pin Definitions
GND Ground (Vss)
5 V 5 VDC (Vdd)
SIG Signal (I/O pin)
The PING))) sensor has a male 3-pin header used to supply
ground, power (+5 VDC) and signal. The header may be plugged
into a directly into solderless breadboard, or into a standard 3-
wire extension cable (Parallax part #800-00120).
