Ultrasonic Distance Measurement Control Board Rangefinder Digital Display for HC-SR04

Key Features:

1. HC-SR04 Ultrasonic Sensor:

   • The board is equipped with the HC-SR04 ultrasonic sensor, which uses sound waves to measure the distance to an object.

   • It works by emitting an ultrasonic pulse and measuring the time it takes for the pulse to bounce back after hitting an object.

2. Digital Display:

   • The device includes a digital display (typically an LED or LCD screen) that shows the distance measurement in centimeters or inches.

   • The display shows real-time measurements, making it easy to read the distance.

3. Control Board:

   • The control board acts as the central processing unit (CPU), controlling the operation of the ultrasonic sensor and processing the distance data.

   • It interprets the signal from the ultrasonic sensor and converts it into a readable digital format for display.

4. Power Supply:

   • The board is powered by a typical voltage of 5V and can be connected directly to an Arduino or other microcontroller platforms for easy integration.

5. Accuracy:

   • The rangefinder provides reasonably accurate distance measurements with a range typically from 2 cm to 400 cm with an accuracy of around 3 mm.

6. Simple Integration:

   • The board is designed to be easily interfaced with a variety of controllers, including Arduino, Raspberry Pi, or other microcontroller-based systems.

   • It usually comes with simple wiring for easy connection to these systems.

7. Versatile Applications:

   • It is commonly used in robotics for obstacle detection, positioning systems, and distance measurement.

   • It can also be used in automation, measurement systems, or any scenario where knowing the distance between two objects is necessary.

How It Works:

1. The ultrasonic sensor emits a high-frequency sound pulse from the transmitter.

2. The sound wave travels through the air and hits an object.

3. The sound wave bounces back and is detected by the receiver.

4. The control board calculates the time it took for the pulse to return.

5. Using the speed of sound and the time delay, the distance to the object is calculated.

6. The result is displayed on the digital screen.

Applications:

• Robotics: For navigation and collision avoidance.

• Measuring Distances: In laboratory setups, warehouses, or any location requiring distance measurement.

• Automated Systems: For positioning or level sensing.

This ultrasonic distance measurement system is widely used for its simplicity, accuracy, and the ability to integrate with various platforms for broader use cases.
