0: Module precision, blind spots (2cm) super close.

1: Voltage: DC5V

2: Quiescent Current: <2mA

3: level output: the output of the high-5V

4: level: the end of 0V

5: Induction Angle: not more than 15 degrees:

6. detection range: 2cm-450cm

7: High precision: up to 0.3cm

Panel wiring, VCC, trig (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.


This product is simple to use, and a Control Port high above a 10US, you can wait for the high output at the receiving port. An output can open the timer can be read when this port goes low timer value for the time ranging be calculated distance. such a continuous cycle of measurement, you move to measure the value we can achieve ~ ~~


The module 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) the signal to return, a high IO output, high duration of

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