diymore DC 5V Waterproof Ultrasonic Distance Sensor Measuring Ranging Transducer Module for Arduino

Model: 8954511   |    Mpn: WU   |    Ean: 0611029136085   |    PartNumber: WU   |   Asin: B01J5KZU8M

Electrical parameters: JSN-SR04T 2.0

Operating voltage: DC 5V

Quiescent current: 5mA

Total current work: 30mA

Acoustic emission frequency: 40khz

Farthest distance: 4.5m

Blind: 25cm

Wiring: + 5V (positive power supply)

Trig (control side) RX

Echo (the receiver) TX

GND (negative)

Module size: 41mm * 28.5mm

Resolution: about 0.5cm

Angle: less than 50 degrees

Working temperature: -10 ~ 70

Storage temperature: -20 ~ 80

Application:

1. Horizontal distance;

2. obstacle avoidance, automatic control;

3. the object approaches, there is a perceived

4. traffic control;

5. security, industrial control;

6. artificial intelligence, and research

The basic working principle:

(1) using IO port TRIG trigger location, to the high level signal of at least 10us;

(2) module automatically sends 8 40KHz Fang Bo, automatic detecting whether a signal return;

(3) a signal return, a high level is output through the IO port ECHO, the time duration of the high level is

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

This module uses the simple method, a control port with a 10US above high level, can wait for high level

output at the receiving port. An output can drive the timer, when this port is low can read the timer value,

this time for the location of the time, can be calculated distance. So constantly cycle test, that can achieve

the measurement of the value of your mobile.

If you need some kind of simple "eye" for a robotics project this ultrasonic sensor could do well for finding and avoiding obstacles!
Use an HC-SR04 ultrasonic sensor to give your robot the perception of distance.
Application:
For collision avoidance projects, obstacle sensing Arduino tracked robot projects,autonomous vehicles and boats, physics lab classes
Features:
-Ultrasound modules/Ranging sensor works, both with Leonardo and mega.Great sensor for simple Arduino-based distance measurements, measuring distances Up to 30' and down to 3 inches.
- A lot of fun using these ultrasonic detectors for sonar on your Arduino powered obstacle avoidance robot.
--Objects as thin as cellophane or aluminum foil can be detected
How to Use:
There are 4 pins out of the module: VCC , Trig, Echo, GND.(Make the following connections from the HC-SR04 to the Arduino, respectively: VCC to 5V; GND to GND; Trig to any digital output; Echo to any digital input.)
The all process is : pull the Trig pin to high level for more than 10us impulse , the module start ranging ; finish ranging , If you find an object in front , Echo pin will be high level , and based on the different distance,it will take the different duration of high level. So we can calculated the distance easily.
Distance = ((Duration of high level)*(Sonic :340m/s))/2
Specification
1.Working Voltage : 5V(DC)
2.Static current: Less than 2mA.
3.Output signal: Electric frequency signal, high level 5V, low level 0V.
4.Sensor angle: Not more than 15 degrees
5.Detection distance: 2cm-450cm
6.High precision: Up to 0.3cm
7.Input trigger signal: 10us TTL impulse
8.Echo signal : output TTL PWL signal
9.Accuracy:+/-0.1cm(vary depending on the clock resolution real-time latency of the OS you use.)
Mode of connection:
1.VCC
2.trig(T)
3.echo(R)
4.GND

Features

  • Please get the original ultrasonic sensor from" Ardess"! This is a really common sonar-type Ultrasonic Distance Sensor commonly used with Arduino's and raspbery microcontrollers, helping your robot avoid objects with few lines Arduino code.
  • This ultrasonic module is different from the parallax sensor in that it uses the 4 pin connection vs a 3 pin connection. If you use an arduino controller for this it's no problem.
  • The sensor boards are pretty well-built without solder joints and all pins are clearly labeled on the board silkscreen. Legs are compatible with breadboards so it's easy to use for quick prototyping
  • Cheaper alternative,great option for arduino projects!!I'd recommend these range sensors to anyone needing to sense distance for any of there Arduino projects.
