[ the module performance and stability, measure the distance accurately. Can
and foreign SRF05, SRF02 and other ultrasonic ranging module comparable. Module
high-precision, blind (2cm) ultra-close, stable range is the success of this
product to the market a strong basis!

2 main technical parameters: 1 : Voltage: DC5V 2 : Static current: less than 2mA
3 : level output: high- 5V 4 : level output: the end of 0V 5 : Induction Angle:
not more than 15 degrees 6 : detection range: 2 cm & lt -45 0cm




7: High precision: up to 0.3cm

Wiring, VCC, trig (control side), echo (receiver), GND

This product uses the method: a control port send a 10US more than the high, you
can wait for the high output at the receiving port has an output on a timer can
start counting, when this port goes low can read timing. The value of this time
for the range of time, can be calculated from the distance. Such a continuous
cycle of measurement, you can move the value of the measurement ~ ~

Module works:
(1) using IO trigger ranging, to at least 10us of high-level signal;

(2) the module automatically sends eight 40khz square wave, automatic detection
of whether there is signal return;

(3) there is a signal return, through the IO output a high level, high duration
is

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

This module provides a full set of ranging procedure: C51 , PIC18F877,
ultrasonic LCD1602 display, ultrasonic LCD12864 display, digital display, serial
display, ranging reference program .
