การใช้งาน : you can wait to receive high output port. A timer can be opened with the output timing, when the port goes low when the timer value can be read this when the time for this distance, only calculate the distance. This constant cycle of measurement, you can reach the value of the mobile measurement ~ ~
Module works:
The IO trigger location, the high signal to at least 10us;
the module automatically sends eight 40khz square wave, automatically detects whether a signal return;
a signal back, through the IO of a high output, high duration is Ultrasonic time from launch to return. Test distance = (time * High speed of sound (340M / S)) / 2;
