Intelligent Barrowload Diy Robot Kit , Mount HC-SR04 Cartoon
1. the module performance is stable, measure the distance
2. The product is simple to use
3. high-level signal
4. hot sale
5. reliable quality
Board wiring , VCC, trig ( control side ), echo ( receiving end ),
out ( empty legs ), GND
Note : TRIP pin is internally pulled 10K resistor , using SCM TRIP
IO port pin is pulled low , and then give a more than 10us pulse
OUT pin as an anti-theft module, this module switch output pin ,
ranging module without this pin !
Note : The module should be re- energized circuit board inserted
Fortunately , avoid high malfunction , if they have a re- energized
This module provides ranging procedure : C51, PIC18F877, Yoshitatsu
microcontroller, three kinds of MCU Test Reference .
The module performance is stable, measure the distance accurately .
Energy and foreign SRF05, SRF02 ultrasonic distance measuring
module and other comparable . Module precision, blind spots (2cm)
super close , stable ranging success of this product to the market
is strong under ! This module is fully Qian Yung- GH-311 anti-theft
The product is simple to use , a control port made a high of more
than 10US , you can wait to receive high output port . A timer can
be opened with the output timing , when this port goes low when you
can read timer value , this time on the time for this distance ,
only calculate the distance. this constant cycle of measurement ,
you can reach the value of the mobile measurement.
( 1) The IO trigger distance , high-level signal to at least 10us ;
( 2 ) the module automatically sends eight 40khz square wave ,
automatically detects whether a signal return ;
( 3 ) a signal back , through the IO outputs a high level, the
duration of high level is
Ultrasonic time from launch to return . Test distance = ( time *
High speed of sound (340M / S)) / 2;
This module provides a full set of ranging process : C51,
PIC18F877, ultrasonic LCD1602 display , ultrasonic LCD12864 display
, digital display , serial display, ranging reference program.
