LED Reverse Parking Sensor Product Details
I. Product Overview
The LED reverse parking sensor is an intelligent safety system designed to enhance vehicle reversing safety. Comprising ultrasonic sensors (probes), a control unit, and a high-visibility LED display, this system uses ultrasonic technology to detect rear obstacles in real-time. It provides dual alerts through dynamic LED color changes and audible beeps, allowing drivers to judge distances accurately and navigate tight parking spaces with confidence.
II. Working Principle
The LED reverse radar operates based on the principle of ultrasonic distance measurement. When the vehicle is shifted into reverse gear, the system is activated. The ultrasonic sensors installed on the front and rear bumpers emit ultrasonic pulses. After encountering an obstacle, the ultrasonic waves are reflected and received by the sensors, which then transmit the signals to the control unit.
The control unit calculates the distance between the vehicle and the obstacle based on the time difference between the emission and reception of the ultrasonic waves. It then converts this distance information into electrical signals to drive the LED display screen. The closer the vehicle gets to the obstacle, the smaller the number on the display screen becomes. The color of the display changes in sequence from green (indicating safety), to yellow (warning), and then to red (danger). Meanwhile, the buzzer emits alarm sounds at different frequencies to help the driver quickly and accurately understand the real - time distance and avoid collisions.
III. Key Features
1.Precise Distance Measurement**: With the ultrasonic sensors, it can accurately detect obstacles within 0.3 - 2 meters behind the vehicle and provide precise distance data.
2.Dual Alarm System:
LED Light Bar Display: It offers three - color dynamic prompts (green for safety → yellow for warning → red for danger).
Buzzer Alarm: As the distance to the obstacle shortens, the frequency of the buzzer sound increases. In an emergency, it will emit a continuous long beep.
3.Blind Spot Coverage: It can effectively identify low - lying obstacles (such as bollards, pets, and children).
4.Intuitive LED Presentation: Through a clear LED display screen, it can present the distance to the obstacles behind the vehicle in real - time in the form of graphics or numbers.
