Electromagnetic parking sensor

Types of Electromagnetic Parking Sensor

Electromagnetic parking sensors are devices that aid drivers in parking their vehicles safely and accurately. These sensors utilize electromagnetic waves to detect obstacles and provide real-time information to drivers. Generally, they fall into two categories:

• Ultrasonic Parking Sensors

  Ultrasonic parking sensors are the most common type of sensor in vehicles. They operate using sound waves to identify objects around the vehicle. Here's how they work:

  The sensors mounted on the vehicle’s bumpers emit sound waves continuously. When these sound waves hit an obstacle, they bounce back to the sensor. The system calculates the distance to the obstacle based on the time it takes for the sound waves to return. If an object is detected, the system activates an audible alert that gets louder as the vehicle approaches the obstacle.

  Additionally, the sensor can display visual warnings on the screen, showing the proximity and location of the objects. Some advanced ultrasonic sensors have multi-directional capabilities, allowing them to detect obstacles from various angles, improving overall safety. They also have adjustable sensitivity features that enable the sensors to be fine-tuned to detect only significant obstacles, reducing false alarms from small objects.

• Electromagnetic Parking Sensors

  Electromagnetic parking sensors are advanced sensors that use electromagnetic waves to assist with parking. They are typically more precise than conventional sensors. These sensors can detect both moving and stationary objects, providing a comprehensive understanding of the parking environment.

  Electromagnetic sensors are often integrated into the vehicle's guidance system. They can provide visual information about the surroundings on a display screen, helping drivers make informed decisions while parking. Moreover, they can automatically control the steering of the vehicle, allowing for automated parking in tight spaces. Additionally, they can analyze the environment and calculate the optimal parking path, assisting with parallel parking.

Specifications and Maintenance of Electromagnetic Parking Sensors

Below are some specifications of the electromagnetic parking sensor that are important to business buyers:

• Detection Range

  The detection range indicates the maximum distance the sensor can reach to avoid obstacles. The average detection range is 1.5 meters, but this can change depending on the make and model.

• Working Frequency

  Electromagnetic parking sensors emit low-frequency sound waves to detect obstacles. This is referred to as the working frequency. The average working frequency is 40 HZ to 70 HZ.

• Operating Voltage

  The operating voltage refers to the amount of power needed for the sensors to work properly. Most parking sensors need about 12 volts, which they can draw from the car's battery.

• Current Consumption

  Current consumption refers to the amount of current the sensor uses. The average current consumption of parking sensors is 20 mA when they are active and 5 mA when they are in standby mode.

Below are the maintenance requirements for the electromagnetic parking sensor:

• Regularly check the parking sensor to see if there are any signs of damage, such as cracks or breaks.
• Clean the sensor regularly to remove any dirt, grime, or debris that may interfere with its operation. Use a soft cloth or brush and mild soap and water.
• Ensure the wiring is secure and not frayed or damaged.
• Inspect the control module to ensure it is functioning properly.
• If there are any problems with the sensor, please consult the manufacturer's manual.

How to Choose Electromagnetic Parking Sensor

Choosing the right electromagnetic parking sensors for cars requires careful consideration of several factors to ensure they meet safety needs and expectations. Here are some tips:

• Sensor coverage: When choosing an electromagnetic parking sensor, consider its coverage. Select a sensor with larger coverage to have a safe parking experience. Also, consider the vehicle's size and parking habits and choose a sensor that fits perfectly.
• Sensor sensitivity: Sensitive sensors can detect even minor obstacles, while less sensitive ones may only pick up larger objects. Choose the sensitivity level according to the user's preferences, obstacles frequently encountered while parking, and the environment's characteristics.
• Display and feedback: Consider what feedback one needs when selecting an electromagnetic parking sensor. Choose a sensor with a visual display if one prefers to see the distance on a screen. Alternatively, opt for audio feedback if one prefers hearing alerts. Select a sensor providing both audio and visual feedback for maximum convenience and safety.
• Ease of installation: Choose sensors that are easy to install and don't require professional help. If planning to install the sensors personally, consider the installation instructions and whether the sensors come with all the necessary components. Also, choose sensors with clear installation instructions to install the sensors correctly and quickly.
• Quality and durability: Select high-quality parking sensors built to last. Choose parking sensors made of strong materials that can withstand different weather conditions. Also, consider the warranty offered by the manufacturer. A long warranty period is a sign of quality and durability of the product.

How to DIY and replace electromagnetic parking sensor

The installation process of an electromagnetic parking sensor system is very easy and can be done by anyone irrespective of their technical knowledge. The steps are as follows.

• 1. Clean the surface where the sensors will be mounted. This is important so that the sensors won’t fall off when the surface gets dirty.
• 2. Peel off the double-sided tape on the back of the sensor.
• 3. Stick the sensors on the car’s rear bumper. Usually, there are 2 to 4 sensors that need to be installed, so make sure they are all placed on the designated locations.
• 4. Connect the parking sensor system to the car’s power supply. Some systems might connect to the reverse light cable instead of the power supply. So, it’s really important to read the user manual and installation guide to ensure the correct connection is made.
• 5. Turn on the parking sensor system to make sure it’s working properly before closing everything up.

It’s important to note that the installation process may vary a little depending on the brand and model of the parking sensor. Apart from that, some brands come with DIY-friendly kits, while others don’t. Therefore, look for kits that are designed for DIY installations if planning to install the sensors by oneself.

Furthermore, always follow the manufacturer’s instructions when installing an electromagnetic parking sensor. The above steps are just a general guide to help understand the process better.

Q and A

Q1: How are electromagnetic parking sensors different from traditional ultrasonic sensors?

A1: Traditional ultrasonic sensors use sound waves to detect objects, while electromagnetic sensors use electromagnetic fields. This makes electromagnetic sensors effective in detecting stationary objects that might not reflect sound waves well.

Q2: Can these sensors be installed on all vehicle types?

A2: While they are designed for most vehicles, installation difficulty may vary. Larger vehicles like trucks may require additional components due to their size. It's best to consult the manufacturer's guidelines.

Q3: Do electromagnetic parking sensors require maintenance?

A3: Generally, they require less maintenance than other types. However, keeping the sensor clean and free from dirt or debris that could interfere with its function is important.

Q4: Can they detect small objects like bicycles?

A4: While they can detect most objects, the sensor's sensitivity level determines small objects like bicycles. If the sensors are not calibrated to detect small objects, there might be a risk of collision.

Q5: Are there any environmental conditions that can affect the performance of these sensors?

A5: Extreme weather conditions like heavy rain, snow, or ice can affect the sensor's performance. Similarly, the presence of metal objects nearby can interfere with its electromagnetic field, leading to false alarms or reduced detection range.
