This datasheet presents things related to time measurements, sensor elevation, ultrasonic microphone, temperature, echo time, input trigger, distance, ping range, distance measure, ultrasonic, measurement, and echo pulse. Lots of explanation such as object, conversion, ultrasonic distance, ultrasonic distance sensor, measure, ping ultrasonic distance, sensors and applications, echo return, conversion factor, trigger, and frequency tones are described in this datasheet.
Inside the datasheet we can find info related to the ping sensor, echo, measure object distance, distance sensor, ping, sensors, parallax, ping ultrasonic, centimeter measurements, servo, trigger pulse, and ping sensor. Here are selected from the datasheet:
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®, SX or Propeller chip, 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
Even more, the datasheet gives the reader information regarding smart sensors, detect distance, range, supply, distance measurements, ultrasonic detector, measurements, sound, distance value, output pulse, and sensor.
