6.Artificial intelligence, and research
The basic working principle:
1) using IO port TRIG trigger location, to the high level signal at least 10us.
2) module automatically sends 8pcs 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 x speed of sound (340M/S)) /2.
