Ultrasonic sensors overcome many of the weaknesses of IR sensors – they provide distance measurement regardless of color and lighting of obstacles.

They also provide lower minimum distances and wider angles of detection to gaurantee that obstacles are not missed by a narrow sensor beam.

Distance measurements can be made with microcontrollers in a straightforward manner:

Send a 10 uS wide pulse to the sensor on the Trigger Pin. The sensor will automatically send out a 40 kHz wave.
Begin monitoring the output from the Echo Pin and
When the Echo Pin goes high, begin a timer.
When the Echo Pin goes low, record the elapsed time from the timer and use the following conversion formula:
Distance (in cm) = (elapsed time * sound velocity (340 m/s)) / 100 / 2
Note: we divide distance by 2 because the sensor returns the round trip time, which doubles the distance measurement.
Refer to the timing diagram
