- It is used for detecting the distance to an object using sonar.
- The HC-SR04 uses non-contact ultrasound sonar to measure the distance to an object, and consists of two ultrasonic transmitters (basically speakers), a receiver, and a control circuit
Description: This HC-SR04-Ultrasonic Range Finder is a very popular sensor that is found in many applications where it requires measuring distance and detecting the objects.

This Ultrasonic Sensor module is a transmitter, a receiver and a control circuit in one single pack!! It has a very handy and compact construction. It offers excellent range accuracy and stable readings in an easy-to-use package. Its operation is not affected by sunlight or black material like Sharp rangefinders are (although acoustically soft materials like cloth can be difficult to detect).
The Trigger and the Echo pins are the I/O pins of this module and hence they can be connected to the I/O pins of the microcontroller/Arduino.
When the receiver detects return wave the Echo pin goes high for a particular amount of time which will be equal to the time taken for the wave to return back to the sensor.
Ultrasonic Ranging Module HC-SR04 provides 2cm-400cm non-contact distance sensing capabilities, ranging accuracy up to 3mm.
Applications of Ultrasonic Sensor:Ultrasonic Sensor is used for calculating the distance between the sensor and the object. It is mostly used for calculating the acceleration, velocity and position of the sensor attached to the device.
IN THE BOX:
1 X Ultrasonic Sensor
I gave 4 star because the module gave me me a bit trouble so l l replaced it they told ok for replacement
It's works with Arduino confirmed but if you want pin point accuracy , Ultra Sonic Sensor is not for you it's accuracy is normally accurate to not crash enywhere.Want more information write a question or search it
great product. can identify distant objects also. go for it if searching something like this.
It can dectet objects upto 4 mtrs. which i think is great in this range. nice buy.
