3, high accuracy;
4, strong anti-interference;
5, closed-end integration with waterproof wire probe for wet, harsh measurement occasions.

Applications:

1, the horizontal distance;
2, obstacle avoidance, automatic control;
3, the object approaches, there is a perceived
4, traffic control;
5, security, industrial control;
6, artificial intelligence, teaching and research

The basic operating principle:

(1) using IO port TRIG trigger ranging to at least 10us high-level signal;

(2) module automatically sends eight 40khz square wave and automatically detect whether a signal return;

(3) the signal returned by IO port ECHO outputs a high level, high duration is Ultrasonic time from launch to return. Test distance = (high level time * sound velocity (340M / S)) / 2;
This module is simple to use, a control port to send a 10US high above, you can wait for high output at the receiving port. There are an output of the timer can be opened, when this port goes low can be read the timer value, at this time for this distance of time before calculating the distance. this constant cycle of measurement, which can measure up to the value of your move.
