Parking sensors kit Amio AMI-01021 — 4 silver ultrasonic sensors with buzzer for reversing

Amio AMI-01021 is a parking sensor kit designed to assist drivers during reversing and low-speed manoeuvres. The set contains four silver ultrasonic sensors and an audible buzzer unit. The sensors are intended for mounting in a rear bumper to detect obstacles behind the vehicle and provide progressive distance warnings to the driver.

Advantages

The kit provides audible feedback via a buzzer that changes tone as distance decreases, allowing the driver to estimate proximity without visual contact. Four sensors cover a wide rear area to reduce blind spots and improve detection of obstacles of varying height. The sensors are compact and finished in silver to match many bumper colours, and the system is compatible with standard 12 V vehicle electrical systems.

Suitable for

• Assisting in reversing and parking in urban and confined spaces
• Reducing risk of low-speed collisions with unseen obstacles
• Retrofit installation on passenger cars and light commercial vehicles with a 12 V electrical system

Key specifications

• Sensor type: ultrasonic distance sensors
• Quantity: 4 sensors plus one buzzer unit
• Finish: silver-coloured sensor housings
• Alert type: audible buzzer with progressive tone/pulse frequency
• Mounting: bumper-mounted with wiring to buzzer/control unit
• Operating voltage: compatible with standard 12 V vehicle systems

How to use

Install the four ultrasonic sensors into the rear bumper according to the vehicle manufacturer’s guidelines and the kit’s installation instructions. Route wiring from each sensor to the buzzer/control unit and connect the unit to the vehicle’s 12 V power supply and reverse-light trigger so the system activates automatically when the vehicle is put into reverse. After installation, test the system by reversing toward a stationary object and observe the buzzer’s change in tone as distance decreases; adjust sensor positions or angles if necessary to ensure reliable detection.

Usage recommendations

Ensure sensors are mounted at the recommended height and securely sealed against moisture and dirt. Regularly clean sensor surfaces to maintain detection accuracy. Use the parking sensor kit as an aid—continue to check mirrors and surroundings visually while reversing.
