 Product description:

   HC-SR04+ is a wide voltage working ultrasonic ranging module. Module dimensions and software are fully compatible with the old version of HC-SR04; You can switch seamlessly with the older version of HC-SR04. Low operating voltage as low as 3V enables direct connection with the 3.3V powered MCU.

   The performance of this module is stable and the distance is measured. It can be comparable with the foreign SRF05,SRF02 and other ultrasonic ranging modules. High precision module, super close blind area (2cm), stable ranging is a strong basis for the success of this product to the market! This module fully accommodates the GH-311 anti-theft module

 

Main technical parameters:

1: service voltage: DC5V 2: static current: less than 2mA

3: level output: high 5V 4: level output: bottom 0V

5: induction Angle: no more than 15 degrees 6: detection range: 2cm-510cm

7: High precision: up to 0.3cm

 

Board connection mode, VCC, TRIG (control end), ECHO (receiving end), OUT (empty pin), GND

 

Note: TRIP pin is the internal pull 10K resistance, use the IO port of MCU to pull down the TRIP pin, and then give a pulse signal more than 10US.

OUT foot for this module as the anti-theft module when the switch output foot, ranging module does not use this foot!

 

Note: THE module SHOULD be plugged into the circuit board before ENERGIZING, to avoid high level misoperation, if it occurs, it can be solved by re-ENERGIzing.

 

This module can provide ranging program: C51, PIC18F877, Yilong microcontroller, three MCU test reference.

 

Working principle of URF04 module:

(1) Using IO trigger ranging, to give at least 10US high level signal;

(2) The module automatically sends 8 square waves of 40khz to automatically detect whether there is a signal return;

(3) When a signal returns, a high level is output through IO, and the high level lasts for the time from ultrasonic emission to return.

 

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

 

This product is simple to use. If a high level above 10US is sent from a control port, it can wait for high level output at the receiving port. An output can be opened timer timing, when this port into a low level can read the value of the timer, at this time for the ranging time, can calculate the distance. This constant periodic measurement can reach the value of your moving measurement ~~

 

Working principle of the module:

(1) Using IO trigger ranging, to give at least 10US high level signal;

 

(2) The module automatically sends 8 square waves of 40khz to automatically detect whether there is a signal return;

 

(3) When a signal returns, a high level is output through IO, and the duration of the high level is

 

The time from emission to return of the ultrasonic wave. Test distance =(high level time * sound speed (340M/S))/2;

 

This module can provide a full range ranging program: C51, PIC18F877, ultrasonic LCD1602 display, ultrasonic LCD12864 display, digital tube display, serial port display, ranging reference program.
