Automotive sensor is widely used, such as: 1, automotive sensors offer, gasoline indicator is realized by the level sensor, the level sensor utilizing high and low level converted to a digital signal from the meter can be easily 2 on the reading, what automotive sensors, temperature sensors, temperature sensors through temperature node is installed in the tank, when the water temperature is too high or too low also can call the police, Jiangxi automotive sensors, but also from the display instrument directly read. 3, car air conditioning, car air-conditioning is installed in the car by a temperature sensor to control the temperature sensor has a temperature setting, when the temperature is too low to start automatically when the temperature exceeds the working mechanism of the sensor and automatic cooling rotary soft iron magnetic sensors, coils and permanent magnets stationary. Measuring gear formed of a conductive material mounted on a rotating body measured, automotive sensors classification, each turned a tooth, measuring changes in magnetic resistance formed between the gear and a soft iron flux also changed once. Electromotive force induced in the coil change in frequency (pulses) equal to the measured speed of gear teeth and on the product. Hall Hall effect sensors ⒈ semiconductor or metal sheets are placed in a magnetic field, when a current (magnetic field perpendicular to the sheet plane direction) flows, electromotive force is generated in a direction perpendicular to the magnetic field and electric current, a phenomenon known as Huo Hall Effect. ⒉ Hall element germanium material commonly Hall (Ge), silicon (Si), indium antimonide (InSb), indium arsenide (InAs) and so on. N-type germanium easy manufacturing, Hall coefficient, temperature performance, good linearity; linearity of the P-type silicon preferably, Hall coefficient, temperature performance with the N-type germanium, but low electron mobility, with a load capacity than poor usually do not make a single Hall element.
