Module cảm biến khoảng cách siêu âm HY-SRF05 5pin DC 5V thay thế cho giao diện điện SR04 tại Lotte Market

Giới thiệu Module cảm biến khoảng cách siêu âm HY-SRF05 5pin DC 5V thay thế cho giao diện điện SR04 tại Lotte Market

This module has stable performance and accurate distance measurement. It is comparable to foreign ultrasonic ranging modules such as SRF05 and SRF02. The high precision of the module, the ultra-close blind zone (2cm), and the stable ranging are the powerful basis for this product to successfully enter the market!

The main technical parameters:
1: Use voltage: DC5V
2: Quiescent current: less than 2mA
3: Level output: high 5V
4: Level output: bottom 0V
5: Induction angle: no more than 15 degrees
6: Detection distance: 2cm-450cm
7: High precision: up to 0.3cm

Wiring mode, VCC, trig (control terminal), echo (receiving terminal), GND

How to use this product:
A control port sends a high level above 10US, and you can wait for a high level output at the receiving port. Once there is an output, you can start the timer to count. When this port becomes low, you can read the timer value. Time is the time of this range measurement to calculate the distance. Such continuous periodic measurement can reach the value of your mobile measurement~~

The working principle of the module:
(1) Use IO to trigger the ranging and give a high level signal of at least 10us;
(2) The module automatically sends 8 40khz square waves and automatically detects whether there is a signal return;
(3) There is a signal return, a high level is output through IO, and the duration of the high level is

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

This module can provide a full set of ranging programs: C51, PIC18F877, ultrasonic LCD1602 display, ultrasonic LCD12864 display, digital tube display, serial port display, etc., distance measurement reference program.
