A sensor is an electronic device that detects and measures a physical quantity such as light sound heat motion or pressure and converts it into a digital or analog signal that can be read by a computer. Sensors are used in a wide variety of applications from monitoring heart rate and blood pressure to detecting smoke and motion.
Car sensors are used to detect a variety of information about the vehicle and its surroundings. There are sensors to detect engine speed engine temperature tire pressure oil level and coolant level. There are also sensors to detect the position of the steering wheel the accelerator pedal and the brake pedal. In addition there are sensors to detect the presence of objects in the path of the vehicle such as other vehicles pedestrians animals and obstacles.
The data from the sensors is used by the computer to control the engine the brakes the steering and the accessories. The computer can also use the data to display information to the driver such as the speed the engine temperature the tire pressure and the oil level.
Some sensors are passive meaning they do not require power to operate. For example a pressure sensor can be made with a balloon that expands when the pressure increases. The expansion of the balloon is detected by a gauge that is connected to the sensor.
Other sensors are active meaning they require power to operate. For example an infrared sensor emits a beam of infrared light and detects the reflected light to determine the distance to an object.
Sensors can be either digital or analog. A digital sensor converts the physical quantity into a digital signal that can be read by a computer. An analog sensor converts the physical quantity into an analog signal that can be read by a meter or other device.
Digital sensors are more common because they are easier to interface with computers. Analog sensors are more accurate but they require more processing to convert the signal into a digital form that can be read by a computer.
