(1) the IO trigger ranging, to at least 10 us high level signal;
(2) module automatically send eight 40 KHZ of square wave, automatic testing if it has any signals return;
(3) a signal to return to, through the IO output top level, the high level of the last time is
From the launch ultrasonic returned to time. Test distance = (high level time * sound velocity (340 M/S)) / 2;
This module can be to provide a full range of ranging procedure: C51, PIC18F877, ultrasonic LCD1602 showed that ultrasonic LCD12864 display, digital pipe display, serial ports display, ranging reference program.
