This module uses the simple method, a control port with a 10US above high level, can wait for high level
output at the receiving port. An output can drive the timer, when this port is low can read the timer value,
this time for the location of the time, can be calculated distance. So constantly cycle test, that can achieve
the measurement of the value of your mobile.
