How Does a Car Backup Sensor Work?
What is a Sensor?
Sensors measure a physical quantity, such as distance, and convert it to an electrical signal for a receiver to interpret. In a reverse sensor, the physical quantity is the distance between the rear fender and the obstacle. This is converted to an electronic signal and sent to a receiver, which will give a warning sound or light. Other cars will actually give the physical distance. Some cars have a camera and a screen on the dashboard for viewing
How Does It Work?
Car sensors emit radio waves. The sensor measures the time it takes for the radio wave to hit the object and return. As the sensor moves closer to the object the time is decreased. The sensor converts this to an electrical signal and sends it to the receiver, which converts it to a readout or alarm
Car sensors vary in price, due to the quality and form of the readout. A simple red light may be cheaper than a digital read out that shows distance in feet or those with a camera. As of 2010, the price range is $20 to $150
How Do Parking Sensors Work?
What is a Sensor?
When someone talks about a sensor, he is probably referring to a tool that allows him to measure a change in an object or thing. That object could be movement or change in air pressure or a combination of the two. Sensors can be made of virtually anything. Plastic, aluminum and other thin conductors are common material types. For sensors to work effectively, they usually are mounted on a fixed object or source. There are, however, wireless options available, too
A parking sensor is a safety device that can help people recognize various roadway dangers. People often attached them behind their rear vehicle tail lights. They generally work by sending out or receiving radio waves, much like a radio or radar gun. A mini-computer inside a sensor box registers electromagnetic waves that bounce off the surface of that given object. Some parking sensors can determine how far away an obect is by looking at the length or frequency of the wave emitted by the object. Certain waves along the electromagnetic spectrum have certain lengths and sizes. A parking sensor can measure those wave types and tell how large, small or fast an object is moving. Large objects essentially emit different sizes of energy wavelengths. Large objects that move very fast reflect a totally different carrier wave signature. The same is true of smaller objects, as well
Ultrasonic and Wireless Parking Sensors
Older model parking sensors often had difficulty in adverse weather conditions. It is because of this difficulty that many parking sensors today use ultrasonic and wireless technology. Ultrasonic waves are generally very high in frequency and short in length. What this means is that they are very strong and can diffuse through various substances, more so than waves used in traditional types of parking sensors. A transducer is responsible for emiting an ultrasonic beam from a sensor box. Because ultasonic waves cannot be heard by the human ear, sensor boxes usually are equipped with an alert device inside the box itself. They can also be linked to either a TV monitor or camera-type device. Conversely, some consumers claim that ultrasonic technology is too cumbersome. To install a parking sensor, you need to have several different sensors placed either behind a tail light or car bumper. Consumers often report that eletromagnetic parking sensors require less work to install and less maintenance
