1, this module has stable performance, accurate measurement of the distance. Can foreign SRF05, SRF02 and other comparable ultrasonic ranging module.High precision module, blind (2cm) super close, stable ranging is strong according to the products to market success! This module is fully compatible with GH-311 security module Abraham

2 main technical parameters:
 1The use of voltage:DC5V 2Static current: less than2mA
 3High level output:5V 4Output: the bottom level:0V
 5Induction angle: no more thanFifteendegree6Detection range: 2CM-450cm

     7:High precision: up to 0.3cm

Board wiring, VCC, trig (control side), echo (receiver), out (empty feet), GND

This OUT foot switch output module as anti-theft module feet, ranging module without this pin! 

Note: the module should be plugged in the circuit board to be re energized, to avoid generating a high level of error, if produced, re energized to solve the problem.

This module can provide ranging program:C51, PIC18F877Yilong, microcontroller, test reference three MCU.

3, the working principle of URF04 module:

(1) using IO trigger ranging, high level signal to at least 10us;

(2) module automatically sends 8 40KHz Fang Bo, automatically detect whether the signal return;

(3) a return signal, outputs a high level by IO, the duration of the high level is the ultrasonic from launch to return.

Test (distance = high level time * sound (340M/S)) /2;   

Simple use of this product, a control port a 10US more than the high level, you can wait for high output level in the receiving port. A output can open the timer, when the port is low you can usually read the timer value. At this point, we the ranging time, calculate the distance. This constant cycle detection, you can reach your mobile measurement value ~ ~ 

(1) using IO trigger ranging, high level signal to at least 10us;

(2) module automatically sends 8 40KHz Fang Bo, automatically detect whether the signal return;

(3) a return signal, outputs a high level by IO, high level duration is

Ultrasonic from launch to return.Test distance (= high level time * sound (340M/S)) /2;  

This module provides a full set of ranging program: C51PIC18F877, LCD1602, ultrasonic ultrasonic display, LCD12864 display, digital display, serial display, location reference program.
