Tronix365 is dedicated to fostering innovation in the field of electronics. One of our standout products is the HC-SR04 Ultrasonic Range Finder, known for its versatility and reliability in distance measurement and object detection.

Introduction to the HC-SR04 Ultrasonic Sensor

The HC-SR04 is a small ultrasonic sensor designed for precise distance measurement in various applications. It consists of an ultrasonic transmitter and receiver on the front, functioning similarly to the sonar systems used by bats and dolphins. By emitting ultrasonic waves and detecting their return, it offers a contactless distance measurement solution.

Features and Advantages

  • Range and Accuracy: The HC-SR04 can measure distances from 2 cm to 400 cm with an accuracy of up to 3 mm, making it suitable for applications ranging from robotics to home automation.

  • Reliable Performance: Unlike other rangefinders, the HC-SR04 remains unaffected by sunlight or dark surfaces, although it may face challenges with acoustically soft materials like cloth. This ensures consistent and dependable readings across different environments.

  • Seamless Integration: The sensor comes with Trigger and Echo pins for easy connection to microcontrollers such as Arduino. The Echo pin goes high for a duration proportional to the ultrasonic wave's return time, simplifying distance calculations.

Setup and Usage

You can easily mount the HC-SR04 using a bracket available at Tronix365.com. Here is a quick wiring guide:

  • +5V (Positive)

  • Trig (Control)

  • Echo (Receive)

  • GND (Negative)

By following these steps, you can seamlessly integrate the HC-SR04 into your projects!
