Ultrasonic Distance Sensor Description:
Ultrasonic Distance Sensor provides very short (2CM) to long-range (4M) detection and ranging. The sensor provides precise and stable non-contact distance measurements from about 2cm to 4 meters with very high accuracy.
The ultrasonic sensor can easily be interfaced to microcontrollers where the triggering and measurement can be done using Single I/O pin. The sensor transmits an ultrasonic wave and produces 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.
This UltraSonic Distance Sensor is perfect for any number of applications that require you to perform measurements between moving or stationary objects.
