The GH-311 ultrasonic Motion 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 BA
SIC Stamp®, SX or Propeller chip, requiring only one I/O pin. The GH-311
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.
•GND Ground (Vss),
•5 V 5 VDC (Vdd)
•SIG Signal (I/O pin)
The GH-311 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 solder less breadboard, or into a
standard 3- wire extension cable
The GH-311 sensor detects objects by emitting a short ultrasonic burst and then listening"
the echo. Under control of a host microcontroller (trigger pulse), the
sensor emits a short 40 kHz (ultrasonic) burst. This burst travels
through the air, hits an object and then bounces back to the sensor. The
GH-311 sensor provides an output pulse to the host that will terminate
when the echo is detected, hence the width of this pulse corresponds to
the distance to the target.
Practical Considerations for Use, (Object Positioning)
The GH-311 sensor cannot accurately measure the distance to an object that: a) is more
than 3 meters away, b) that has its reflective surface at a shallow angle so that sound will
not be reflected back towards the sensor, or c) is too small to reflect enough sound back
to the sensor. In addition, if your GH-311 is mounted low on your device, you may detect
sound reflecting off of the floor.
Target Object Material
In addition, objects that absorb sound or have a soft or irregular surface, such as a stuffed
animal, may not reflect enough sound to be detected accurately. The GH-311 sensor will
the surface of water, however it is not rated for outdoor use or
continual use in a wet environment. Condensation on itstransducers may
affect performance and lifespan of
