HCSR04 Ultrasonic Wave Detector long range ultrasonic sensor
What is Specifications of our long range ultrasonic sensor ?
1 , 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 module
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: Sensor angle : not more than 15 degrees
6 : Detection distance : 2cm-450cm
7: High precision: up to 0.3cm
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 signal .
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 before resolved.
This module provides ranging procedure : C51, PIC18F877, Yoshitatsu microcontroller, three kinds of MCU Test Reference .
3, URF04 module works:
( 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, high duration is Ultrasonic time from launch to return .
Test distance = ( time * High speed of sound (340M / S)) / 2;
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 ~ ~
Module works:
( 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.
