3, the object approaches, there is a perceived
4, traffic control;
5, security, industrial control;
6, artificial intelligence, and research
The basic working principle:
(1) using IO port TRIG trigger location, to the high level signal of at least 10us;
(2) module automatically sends 8 40KHz Fang Bo, automatic detecting whether a signal return;
(3) 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;
