Buzzer Reverse Parking Sensor Product Details
I. Product Overview
The buzzer reverse parking sensor is an essential safety assistant device for vehicles during parking or reversing. Composed of ultrasonic sensors (probes), a control unit, and a buzzer, it accurately detects obstacles around the vehicle and provides clear audible alerts, effectively eliminating the hassle of constant visual checks. It helps overcome blind spots and obscured visibility, significantly enhancing driving safety.
II. Working Principle
When the vehicle shifts into reverse gear, the parking sensor activates automatically. The probes, mounted on the front/rear bumper, emit ultrasonic waves at a 45° angle for comprehensive horizontal and vertical detection. Upon encountering an obstacle, the reflected signal is received by the probes. The control unit calculates the distance based on the time difference between signal transmission and reception.
The buzzer's alarm frequency escalates as the vehicle approaches an obstacle:
- Long-distance (>1.5m): Intermittent low-frequency beeps ("Beep-Beep-")
- Mid-distance (0.5-1.5m): Faster mid-frequency beeps ("BeepBeep-BeepBeep-")
- Close-range (0.3-0.5m): Continuous high-frequency alarm ("BeepBeepBeep!")
This intuitive audio feedback allows drivers to gauge distances effortlessly without relying solely on visual displays.
III. Key Features
1. Smart Distance Detection**: Ultrasonic sensors cover 0.3-2 meters with high precision.
2. Multi-Stage Alerts:
>1.5m: Low-frequency beeps
0.5-1.5m: Mid-frequency beeps
0.3-0.5m: Continuous urgent alarm
3. Blind Spot Coverage: Detects low obstacles (e.g., curbs, pets, children)
