This HC-SR04-Ultrasonic Range Finder is a very popular sensor that is found in many applications where it requires to measure distance and detect objects. The module has two eyes like projects in the front which forms the Ultrasonic transmitter and Receiver. The HC-SR04 ultrasonic sensor uses sonar to determine the distance to an object like bats or dolphins do. This pack contains an HC-SR04 Ultrasonic range finder and a mounting bracket for the fast and easy assembly of your project. The Cartoon Ultrasonic Sensor Mounting Bracket used is made up of Acrylic.

This Ultrasonic Sensor module is a transmitter, a receiver, and a control circuit in one single pack!! It has 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).

Ultrasonic Ranging Module HC-SR04 provides 2cm-400cm non-contact distance sensing capabilities, Ranging accuracy up to 3mm. 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 the 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.

  • Using IO trigger for at least 10us high-level signal
  • The Module automatically sends eight 40 kHz and detect whether there is a pulse signal back
  • IF the signal back, through high level ,time of high output IO duration is the time from sending ultrasonic to returning.
