This sensor is a high performance ultrasonic range finder. It is compact and measures an amazingly wide range from 2cm to 4m. This ranger is a perfect for any robotic application, or any other projects requiring accurate ranging information. This sensor can be connected directly to the digital I/O lines of your microcontroller and distance can be measured in time required for travelling of sound signal using simple formula as below.
Distance = (Echo pulse width high time * Sound Velocity(340M/S)/2) or Distance in cm = (Echo pulse width high time (in uS)*0.017)
The module works on 5VDC input and also gives a output signal directly for detection of any obstacle up to 4M.
