•(1) using IO port TRIG trigger location, to the high-level signal of at least 10us;
•the module automatically sends 8 40KHz Fang Bo, automatic detecting whether a signal return;
•a signal return, a high level is output through the IO port ECHO, the time duration of the high level is
•ultrasonic from launch to return. The test distance = (high level time * speed of sound (340M/S)) /2;
•This module uses the simple method, a control port with a 10US above high level, can wait for a 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…
