Ultrasonic Distance Sensor provides range from very short (2 Centimeters) to long-range (5 Meters) forapplications in detection and ranging. The sensor provides precise and stable non-contact distance measurementsfrom about 2 cm to 5 meters with very high accuracy. 

The ultrasonic sensor can easily be interfaced to microcontrollers where the triggering and measurement can bedone using two I/O pin. The sensor transmits an ultrasonic wave and produces an output pulse that correspondsto the time required for the burst echo to return to the sensor. By measuring the echo pulse width, the distanceto target can easily be calculated.

This Ultrasonic Distance Sensor is perfect for any number of applications that require you to performmeasurements between moving or stationary objects. The trigger input is sent a 10 usec pulse and followed bythat the pulse width on the echo line is measured, the measured pulse width is then converted into distance incm.
