2. Obstacle Avoidance and Automatic Control;

3. Object Proximity and Presence Detection

4. Traffic Control;

5. Security and Industrial Control;

6. Artificial Intelligence, Teaching and Research

 

Basic Working Principle:

(1) Trigger Ranging with Io Port Trig to Give at Least 10us High Level Signals;

(2) the Module Automatically Sends a Square Wave of 8 One 40KHz to Automatically Detect Whether Any Signal Is Returned;

(3) a Signal Is Returned, and a High Level Is Output through the IO Port Echo. the Duration of the High Level Is the Time from Ultrasonic Emission to Return. Test Distance = (High Level Time * Sound Velocity (340 M/s))/2;

This Module Is Easy to Use. a Control Port Sends a High Level above 10us, and You Can Wait for the High Level Output at the Receiving Port. Once There Is an Output, the Timer Can Be Turned on for Timing. When This Port Changes to Low Level, the Value of the Timer Can Be Read. at This Time, the Distance Can Be Calculated Only by Measuring the Distance. With Such Continuous Periodic Testing, You Can Move the Measured Value.

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;

 

4. 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.
