Wiring mode, VCC, trig, echo, GND
How to use this product: if a control port sends a high level of more than 10us, you can wait for the high level output at the receiving port. As soon as the output is available, you can turn on the timer for timing. When the port turns to low power, you can read the value of the timer. At this time, it is the time of this ranging, and then you can calculate the distance. Such continuous periodic measurement can reach the value of your mobile measurement~~
Working principle of the module:
(1) Adopt IO trigger ranging to give at least 10us high-level signal;
(2) The module automatically sends 8 square waves of 40KHz to detect whether there is signal return;
(3) If there is signal return, output a high level through IO, the duration of high level is
Time from transmission to return. Test distance = (high level time * sound speed (340m / s)) / 2;
This module can provide a complete set of ranging program: C51, pic18f877, ultrasonic LCD1602 display, ultrasonic LCD12864 display, digital tube display, serial port display, etc., ranging reference program.
