to:
This sensor can be used for any applications that require measurements between moving or stationary objects. Naturally, robotics applications are very popular but we would also find this product to be useful in security systems. It can used as an infrared replacement,since it can detect transparent objects.

Initial report by [[~jyp243 | Joo Youn Paek]] , 14, FEB, 2006

http://itp.nyu.edu/~jyp243/sensors/img/intro.jpg

Put a paragraph or two here introducing the the sensor. You might want to add an introductory image as well.


!!!Applications

Describe some typical applications of this sensor. You can often get this from the datasheet, but a few examples from companies or individuals who've used it would be useful as well.

!!!Electrical Characteristics [[http://itp.nyu.edu/~jyp243/sensors/pdf/28015-Ping-v1.1.pdf | Datasheet ]]

*Supply Voltage - 5VDC
*Supply Current - 30 mA typ; 35 mA max
*Range - 3 cm ro 3 m(1.2in to 3.3 yrds)
*Input Trigger - positive TTL pulse, 115 uS to 18.5 ms
*Echo Hold-off - 750 uS from of trigger pulse
*Burst Frequency - 40 kHz for 200 uS
*Burst Indicator LED shows sensor activity
*Delay before next measurement - 200 uS
*Size - 22 mm H x 46 mm W x 16 mm D (0.84 in x 1.8 in x 0.6 in)


!!! Pin Descriptions
A male 3-pin header is built-in supplying power, ground, and signal. It allows the sensor to be plugged into breadboard, which is easy to build fixed mounting. Signal pin transforms pulse in and out.


http://itp.nyu.edu/~jyp243/sensors/img/pin.jpg



!!!Microcontroller Connections

I connected signal pin to port.d 1 of the 18F452 microcontroller. Yet any digital pin will transform data succesfully. The microcontroller and the sensor shares the ground. Both receive power from the same supply but connected parallel.

!!!Code Sample

BASIC Stamp example code is available from the [[http://itp.nyu.edu/~jyp243/sensors/pdf/28015-Ping-v1.1.pdf | Datasheet ]]. I translated to [[Code.Pallarax PING))) Ultrasonic Distance Sensor #28015 | PicBasicPro]], the software available for me.



!!!Typical Behavior

Since it senses non-contect distance measurement, testing in a protected environment is important. I tested mounting the sensor at the edge of a desk with 320cm x 270cm empty room in the front. Datasheet tells different sensing rage according to the shape of the target.

http://itp.nyu.edu/~jyp243/sensors/img/ping_test.jpg

I tested four different targets. As closer the target accutate the value.


As slim cylinder was the best model to get rational data, I measured the sensing boundary with even slimmer cylinder. I made a long marker pen by attaching the marker pen at the end of 1-inch radius plastic pole. As searching the edge of the sensing area, I could draw the boundary of it.


The result didnít match exactly same dimension as the datasheet but the shape was similar.



!!!Application Notes
