Package Contents:
1 * Ultrasonic Module Distance Measuring Transducer Sensor
The basic working principle:
1) using IO port TRIG trigger location, to the high level signal 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 x speed of sound (340M/S)) /2.
Only the above package content, other products are not included.
Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
