The Vemo Parking Aid Sensor - V20720562 is a product designed to assist drivers in parking their vehicles. It is a sensor that is installed on the rear bumper of a vehicle and uses ultrasonic technology to detect objects in the vehicle's path while reversing. The sensor emits a high-frequency sound wave that bounces off objects and returns to the sensor, allowing it to calculate the distance between the vehicle and the object. This information is then relayed to the driver through an audible warning or visual display, helping them to avoid collisions while parking. The Vemo Parking Aid Sensor is a reliable and convenient tool for ensuring safe and accurate parking.
