10US a control population of more than a high-fat, 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 ~ ~
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;
Asignal 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)) /
This module provides a full set of ranging process: C51, PIC18F877, ultrasonic LCD1602 display, ultrasonic LCD12864 display, LED display, serial display, ranging reference program.
