Note:


(1) using IO trigger distance, the high signal to at least 10us;

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

(3) a signal back, through the IO output a high electrical level, high electrical level duration is: the ultrasound time from launch to return. Test distance = (time of the high electrical level * speed of sound (340M / S)) / 2;
