Automotive sensor signal conditioner with analog output. The following is a list of different types of sensors that are commonly used in various applications. From different types of sensors used in cars, the mass air flow sensor maf is a computercontrolled sensor that calculates the volume and density of the air taken in by the engine. Automotive sensors market by type, application covid19. See figure 252 for a typical type of automotive sensor. Types of car sensors used in automobile engine car from.
It employs a speciallydesigned integrated circuit and a magnet that are sealed into a probetype package for physical protection and costeffective installation into. Require an external source of power excitation voltage that provides the majority of the output power of the signal 2 passive sensors. Speed sensors are machines used to detect the speed of an object, usually a transport vehicle. Almost all modern car engines use a lot of different car sensors to gather the right information to calculate a perfect air fuel mixture for the best fuel economy in all situations. All these sensors are used for measuring one of the physical properties like temperature, resistance, capacitance, conduction, heat transfer etc. Computers and sensors operation,diagnosis, and service. The signals from this type of sensors are detected by charge amplifiers. A resistive sensor reacts to changes in mechanical. Overview of automotive sensors sensors journal, ieee. Both types of sensors use the wellkown halleffect to transform the position information into an electrical signal. This signal in turn relays to the computer data about the condition of the system it controls.
Additionally, two types of mass air flow sensors, five types of exhaust gas oxygen sensors, one type of engine knock sensor, four types of linear acceleration. The sensitivity of a vehicle knock sensor is about 20mvg g9. The deep knowledge in position sensor testing is a must in modern automotive technology diagnostic. The implication for the automobile industry is the.
