PING))) Ultrasonic Distance Sensor (#28015) 

v2.0  2/4/2013  Page 4 of 9 

Test Data 

The test data on the following pages is based on the PING))) sensor, tested in the Parallax lab, while 

connected to a BASIC Stamp microcontroller module.  The test surface was a linoleum floor, so the 
sensor was elevated to minimize floor reflections in the data.  All tests were conducted at room 

temperature, indoors, in a protected environment.  The target was always centered at the same elevation 

as the PING))) sensor. 

Test 1 

Sensor Elevation: 

40 in. (101.6 cm) 

Target:  

 

3.5 in. (8.9 cm) diameter cylinder, 4 ft. (121.9 cm) tall – vertical orientation
