Promata PS02 Car Rear Parking Sensor Kit with Buzzer - Reliable 58KHz

Our review of the Promata PS02 finds it is a practical upgrade for drivers who regularly reverse into tight spots or tow trailers. The kit's single biggest advantage is its combination of 58KHz OE-standard sensors and an auto tow-bar recognition mode, which together reduce false alerts from rear protrusions and provide broader coverage than common 40KHz systems. For anyone fitting a non-invasive aftermarket sensor system to a family car, SUV or light trailer setup, the PS02 delivers clear distance feedback and an easy-to-understand buzzer alarm.

Key Features

• Auto Tow Bar Recognition: Detects and compensates for a fitted tow bar or rear protrusions so alerts remain accurate even with aftermarket fittings installed.
• 58KHz OE Standard Sensor: Uses higher-frequency ultrasonic sensors for improved coverage and better obstacle detection in close quarters compared with lower-frequency alternatives.
• Adjustable Alarm Volume: Lets the driver select low, medium or high buzzer levels so the warning is audible in different cabin and road noise conditions.
• Extended Detection Range: Offers selectable extension of 20 cm or 40 cm to cover rear-mounted items such as spare tyres or bumper-mounted accessories.
• Self Test Function for Faulty Sensors: Performs an internal check and alerts the driver to a sensor fault to avoid unnoticed failures that could reduce safety.

Who It's For

The Promata PS02 is best for drivers who need dependable rear obstacle detection with minimal fuss, especially those who tow or carry rear-mounted equipment that can otherwise trigger false alarms. It is also suitable for owners wanting an OE-style sensor frequency and a straightforward buzzer warning rather than a complex visual display.

It is less appropriate for drivers who require a full visual parking display, camera integration, or wireless smartphone alerts; those buyers should look for systems with screens or camera modules. Professional installers will appreciate the clear function set, while DIY installers should be comfortable routing sensor wiring and mounting the buzzer unit.

Our Verdict
