Arduino and ultra sonic range measurement module or how to measure the pulse time with a hardware timer and an interrupt

SEN136B5B is a Ultra Sonic range measurement from SeedStudio. It can measure the distance by sending a 40k Hz ultra sound impulse via the transmitterĀ  and calculating time needed for echo to reach receiver. Detecting range: 3cm-4m. More information about device.

In the description of module is mentioned that it is compatible with Arduino library, but I decided to write program without using PulseIn command.
