Non-Contact Distance Sensor for Sports Height Measurement Systems
Accurately measuring how high an athlete reaches or jumps is essential in sports training, physical education, and performance evaluation. Traditional mechanical touch boards and contact-based systems often lack accuracy, durability, and 디지털 integration.
A non-contact 거리 센서 offers a modern solution by measuring height without physical contact. Using 광학 거리 측정 technology, the system can detect an athlete’s maximum reach point and display the result instantly on an LCD screen.
This article explains how non-contact distance sensors are used in vertical jump 높이 측정 systems and what to consider when selecting the right sensor for this application.
In practical sports training systems, this type of non-contact height measurement is typically implemented using a compact optical distance sensor designed for fast and accurate measurements.
Application Scenario: Vertical Jump and Reach Measurement
In a typical setup, a non-contact distance sensor is mounted above or in front of the athlete. As the athlete jumps and reaches upward, the sensor continuously measures the distance to the hand or touch surface.
When the athlete reaches the highest point, the system records the minimum measured distance and converts it into height data. The final result is displayed on an LCD screen immediately after the jump.
This type of height measurement system is commonly used in:
- Sports training centers
- Schools and universities
- Fitness testing facilities
- Custom sports equipment projects
Why Use a Non-Contact Distance Sensor?
Non-contact distance sensors provide several advantages over traditional contact-based systems:
- No physical wear – no moving parts or touch elements
- 더 높음 측정 정확도 – consistent and repeatable results
- 빠른 응답 시간 – suitable for dynamic movements like jumping
- Easy digital integration – compatible with controllers and displays
Because the measurement is optical and contact-free, the system remains reliable even after repeated use.
System Architecture Overview
A vertical jump height measurement system based on a non-contact distance sensor typically includes:
- Optical distance sensor
- Microcontroller or embedded controller
- LCD display
- Power supply
- Mechanical mounting structure
The sensor continuously outputs distance data. The controller calculates the height difference between the baseline and the peak reach position, then sends the result to the LCD for display.
Key Sensor Requirements for Height Measurement
Choosing the right non-contact distance sensor is critical for accurate performance.
측정 범위
The sensor must cover the full distance from the mounting position to the athlete’s maximum reach height.
Accuracy and Resolution
Millimeter-level resolution ensures reliable differentiation between multiple jumps.
응답 속도
Fast sampling rates are essential to capture the peak reach during short jump durations.
출력 인터페이스
Digital outputs such as UART, TTL, or RS485 allow easy integration with 마이크로 컨트롤러 and LCD modules.
Ambient Light Resistance
Indoor sports environments often have strong lighting, so the sensor must perform reliably under varying light conditions.
Displaying Height Data on an LCD
Distance data from the non-contact distance sensor is processed in real time and displayed on an LCD screen. Typical display information includes:
- Maximum reach height
- Jump height relative to baseline
- Measurement units (mm or cm)
Instant visual feedback improves training efficiency and user engagement.
Expandability and Future Upgrades
Once a non-contact distance sensor is integrated, the system can be expanded to support:
- Data logging and performance tracking
- Wireless communication
- Athlete profile management
- Integration with training software
This makes non-contact height measurement systems suitable not only for training but also for commercial sports equipment and OEM solutions.
Sensor Technology Considerations
Most non-contact distance sensors used in sports applications are based on optical distance measurement, often implemented using laser-based technology. Compared with ultrasonic alternatives, optical sensors provide higher accuracy and faster response.
For applications requiring precise, repeatable height measurement, optical non-contact sensors are generally preferred.
결론
A non-contact distance sensor provides a reliable, accurate, and scalable solution for vertical jump and reach height measurement. By eliminating physical contact and using optical distance measurement, the system delivers consistent results suitable for sports training and performance evaluation.
