RUS-04 Ultrasonic Module with RGB Light Distance Sensor Compatible HC-SR04 Obstacle Avoidance Sensor Smart Car Robot

Feature:

 

This module has stable performance and accurate measurement distance. 

(1) using IO trigger ranging, to at least 10us of the high-level signal;

(2) the module automatically sends eight 40khz square waves, automatically detect whether there is signal return;

(3) there is a signal return, through the IO output of a high, high duration is the time from the launch to the return of ultrasound.

Test distance = (high time * sound speed (340M / S)) / 2;

This product is simple to use, a control mouth made a 10US above the high level, you can wait for the reception of high-level output. An output can be opened timer, when the mouth becomes low when you can read The value of the timer, this time for the distance of time, can be calculated from the distance. Such a continuous cycle of measurement, you can move the measured value
