HC-SR04 Ultrasonic Sensor Range Finder Wide Range

HC-SR04 Ultrasonic Sensor Range Finder Wide Range

For makers and engineers seeking a reliable ultrasonic sensor arduino solution, this HC-SR04 module stands out with precision detection and long-range capability. It integrates strong sonar performance and is ideal for sonic sensors based automation or simple arduino coding for ultrasonic sensor projects. This HC-SR04-Ultrasonic Range Finder is a very popular sensor that is found in many applications where it requires measuring distance and detecting objects. The module has two eyes-like projects in the front which form 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 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 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. Thanks to this mechanism your ultrasonic sensor arduino setup can read distance in real time. Ultrasonic Ranging Module HC-SR04 provides 2 cm-400 cm non-contact distance sensing capabilities, with a Ranging accuracy of up to 3 mm. It’s a versatile tool among sonic sensors, allowing you to expand your robotics or level-sensing project with confidence. If you’re working on arduino coding for ultrasonic sensor projects, this module fits seamlessly: connect VCC to 5 V, Trig to a digital pin, Echo to another digital pin, GND to ground — then measure the pulse width to calculate distance. This ultrasonic sensor arduino module gives you accurate results for mobile robots, automation kits or educational labs.
