HY-SRF05 SRF05 Ultrasonic ranging module Ultrasonic sensor Quaranteed 100%

This module 1, stable performance, accurate measure of the distance. Can SRF05 and abroad, such as SRF02 ultrasonic ranging module comparable. Module high precision, blind area (2 cm) super close, stable is the product range to the market success of powerful according to!
2 main technical parameters:
1: use voltage: DC5V 2: static current: less than 2 mA
3: level output: high 5 V 4: level output: bottom 0 V
5: induction Angle: no more than 15 degrees 6: detection range: 2 cm-450 cm
7: high precision: 0.3 cm
The wiring way, VCC, trig (control terminals), echo (receiver), GND
This product to use: a control mouth hair a 10 US above the high level, can wait for high level output receiver mouth. A has an output can open timer time, when the mouth into a low power can be read at ordinary times timer values, where you for the ranging time, can calculate the distance. This will continue the cycle, can achieve you move the value of measurement
Module working principle:
(1) the IO trigger ranging, to at least 10 us high level signal;
(2) module automatically send eight 40 KHZ of square wave, automatic testing if it has any signals return;
(3) a signal to return to, through the IO output top level, the high level of the last time is
From the launch ultrasonic returned to time. Test distance = (high level time * sound velocity (340 M/S)) / 2;
This module can be to provide a full range of ranging procedure: C51, PIC18F877, ultrasonic LCD1602 showed that ultrasonic LCD12864 display
