This module is completely modest capacity of GH-311 anti-theft module
Two main technical parameters:
1: Voltage: DC5V 2: Quiescent Current: <2mA
2: level output: the output of the high-5V 4: level: the end of 0V
3: Induction Angle: not more than 15 degrees: detection range: 2cm-450cm
4: High precision: up to 0.3cm
Panel wiring, VCC, trig 's (control side), the echo (receiving end), out (empty feet), GND
Note: 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!
Note: 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.
3 the module URF04 works:
(1) IO trigger ranging to at least 10us high signal;
(2) module automatically sends eight 40kHz square wave, automatically detect whether a signal return;
(3) 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;
HY-SRF05
Description:
This module performance is stable, precise measure distance.Can and foreign SRF05, SRF02 ultrasonic ranging module.Module with high precision, blind area (2 cm) very close, stable range is powerful according to the product to the market success!
The main technical parameters:
1: using voltage: DC5V
2: the static current: less than 2mA
3: high level output: 5V
4: level output: 0V
5: induction Angle: no greater than 15 degrees
6: detection range: 2 cm - 450 cm
7: high precision: up to 0.3 cm
This product use: a mouth sends a high level of more than ten us, you can receive the mouth for high level output. To be able to open the timer timing, an output when the mouth into a low electricity at ordinary times you can read the value of the timer is here for the distance of time, can calculate the distance. So constantly cycle test, you can reach your mobile measuring the value of the ~ ~
Working principle of the module:
(1) the IO trigger range, high level signal for at least 10 us;
(2) module automatically sent eight 40 KHZ square wave, automatically detect whether there is signal to return;
(3) have returned signal, through the IO output high level, the duration of the high level is the time of ultrasonic wave from launch to return. The test distance = (high level of time * sound velocity (340 m/S)) / 2;
