Ardest Measuring Module Ranging Ultrasonic Distance Sensor for Obstacle Avoidance in Arduino Projects Pack of 2 by Ardest

Ardest is a registered trademark b Ardess 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.
