Mô-đun cảm biến khoảng cách sóng siêu âm HC-SR04

Giới thiệu Mô-đun cảm biến khoảng cách sóng siêu âm HC-SR04

100% brand new and high quality
Material: Electronic component
Color: See pictures
Two main technical parameters:
Voltage: 5V DC
Quiescent Current: <2mA
Level Output: the output of the high-5V
Level: The end of 0V
Induction Angle: not more than 15 degrees
Detection Range: 2cm-450cm
High precision: Up to 0.3cm
Panel Wiring, VCC, trig 's (control side), the echo (receiving end), out (empty feet), GND
TRIP-pin internal pull-up 10K resistor, down TRIP microcontroller IO port pin, and then to a 10us pulse signal.
OUT pin for this module as the switch output pin when the anti-theft module, ranging modules do not use this foot!
The module should be inserted Fortunately, the circuit board re-energized, and avoid the high malfunction, if they have re-energized before they solve.
This module can be provided ranging program: C51, PIC18F877 microcontroller Yoshitatsu three MCU test reference.
The module URF04 works:
IO trigger ranging to at least 10us high signal;
Module automatically sends eight 40kHz square wave, automatically detect whether a signal return;
A signal to return to a high IO output, high duration of the ultrasonic time from launch to return.
Test distance = (time high * speed of sound (340M / S)) / 2;
Size: 4.5*2*1.4cm/1.77"*0.79"*0.55"
No Retail Packages
Quantity:1Pc
Note: Due to the difference between different monitors, the picture may not reflect  the actual color of the item. Thank you!
