This datasheet contains explanation such as trigger pulse, output pulse, program, sensor elevation, distance, and measurements. Many discussion regarding output, smart sensors, ultrasonic, ping sensor, and microcontroller are presented inside this datasheet.
In this datasheet the reader can get information regarding distance measurements, input, the ping sensor, ultrasonic distance sensor, sensor, and supply. These are some excerpt 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®, 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
Giving more content, the datasheet presents discussion things like conversion, range, power, distance sensor, and circuit.
