Long range parking sensors are available in different types, and each type has various features that suit different customers' preferences. The types include:
Ultrasonic Parking Sensor
This is one of the most popular types of long-range parking sensors. The sensors make use of sound waves that are above the frequency of human hearing. The system contains a sensor that emits sound waves. When the sound waves meet an object, they bounce back to the sensor, and then the system processes the data and provides information about the distance and shape of the object. Because of the accurate detection capability, ultrasonic parking sensors are widely used in various applications, including vehicle parking assistance. The sensors help the drivers to detect obstacles when parking their cars. Also, the sensors have a long detection range and can detect objects from a distance. As a result, they reduce the risk of collisions and provide a safer environment.
Radar Parking Sensor
Radar parking sensors are also another type of long-range parking sensors. The sensors utilize electromagnetic waves that have a frequency lower than sound waves. The sensors emit radar waves that are not visible and are directed toward objects. When the waves encounter an object, they reflect back to the sensor. The parking sensor analyzes the change in the reflected waves and determines the distance and speed of the object. Because of the long detection range, radar parking sensors can detect objects that are far away. This feature enables drivers to monitor their surroundings and detect potential hazards early. Also, the parking sensors can penetrate various weather conditions like fog, rain, and snow. As a result, they provide consistent performance.
Infrared Parking Sensor
Infrared parking sensors are another type of long-range parking sensors. They measure the infrared radiation that is emitted by objects. The sensors utilize infrared light that is not visible and emits beams toward the surroundings. When the beams encounter an object, they reflect back to the sensor. The change in the reflected light signals is analyzed by the parking sensor and determines the distance and shape of the object. Because of the high sensitivity, infrared sensors can detect even small objects in the path of the vehicle. The sensors can detect obstacles that are close to the vehicle. This reduces the risk of accidents during low-speed maneuvers like parking.
When buying a long-range parking sensor for retail, it is crucial to understand the specifications and maintenance requirements of different models. This will ensure that the stock has something for every client's needs and budget.
Frequency
The ultrasonic sensors emit sound waves at a particular frequency, usually between 40 kHz and 200 kHz. The frequency determines the sensor's ability to detect obstacles and its range. Higher frequencies offer better detection of smaller objects at closer ranges, while lower frequencies provide greater overall range but less sensitivity.
Detection angle
Long-range parking sensors have various detection angles. This is the width of the area covered by the sensor's sound waves. An increased detection angle allows the sensor to identify obstacles over a more extensive region, making it easier to avoid potential dangers while reversing or parallel parking. A broader detection angle, typically between 30° and 60° allows for a more comprehensive field of vision. It is beneficial in crowded parking lots.
Output type
The output type of parking sensors determines how they communicate with the driver. Most models use a visual display on the rearview mirror or dashboard screen to show the distance to obstacles. Others have audible warnings that get louder as the vehicle approaches an object. Some advanced sensors combine both methods, offering a detailed overview of the surroundings and real-time feedback. This ensures that drivers of all experience levels can respond appropriately to detected obstacles.
Power supply
Most long-range parking sensors are powered by the vehicle's electrical system. They require around 12 volts. Some advanced models have a separate battery, allowing for wireless operation and more straightforward installation. Wireless sensors do not need extensive wiring through the vehicle, making them less complicated and affordable.
Material
The long-range parking sensor's housing material affects its durability and ability to withstand environmental conditions. Common materials include plastic, aluminum, and stainless steel. Plastic is lightweight and cost-effective but may not offer much protection against harsh weather or physical damage. Aluminum and stainless steel provide more excellent durability and resistance to corrosion. They are, however, heavier and pricier. Manufacturers often use coated materials to enhance longevity and protect against rust and wear.
Regular cleaning
Maintaining long-range parking sensors is crucial for optimal performance. Like any other car part, they accumulate dirt, debris, and moisture, which interfere with their functioning. Therefore, they should be cleaned regularly. This can be as simple as wiping the sensors with a damp cloth. When cleaning, use mild soap and water to avoid scratching the sensors' surface.
Avoid physical damage
Always handle the long-range parking sensor with care to avoid physical damage. Keep the wiring and connections away from moving parts and moisture to prevent shorts and interference. Ensure that the sensor is mounted securely to avoid vibrations and bumps that can cause it to malfunction. Additionally, periodically check the mounting hardware for any signs of wear or looseness.
Software updates
Some advanced long-range parking sensors have features like adaptive cruise control and require periodic software updates. These updates improve performance and add new features. Follow the manufacturer's instructions for updating the parking sensor software, which may involve connecting the sensor to a computer or downloading updates via USB or Bluetooth.
Check the power supply
Long-range parking sensors are powered by the vehicle's electrical system. Therefore, ensure the wiring and connections are secure and free from corrosion or damage. If the sensor has a separate battery, replace it according to the manufacturer's recommendations.
Regular inspections
Regularly inspect the long-range parking sensor to ensure it is correctly aligned and functioning properly. Check for any signs of wear, damage, or moisture exposure. Test the sensor regularly to ensure it accurately detects obstacles and provides reliable warnings.
