What are the functions of various sensors in automobiles?

The functions of intake, intake pressure and intake flow rate are introduced. Detecting the intake air volume gives the computer data of intake air temperature, and the intake air temperature data is transmitted to the computer water temperature sensor. Testing the water temperature provides a signal for the computer to correct the oil pressure. When the oil pressure is low, it will alarm the position of camshaft and crankshaft, be responsible for oxygen sensing of ignition time and cylinder judgment signal, and be responsible for detecting exhaust gas, which can correct fuel injection and improve exhaust gas. Intake pressure sensor, air flow sensor, bending sensor, oxygen sensor, air temperature sensor and water temperature sensor: deflagration sensor. There are speed sensors, temperature sensors, shaft speed sensors, pressure sensors, rotation angle sensors, torque sensors and hydraulic sensors. Vehicle speed sensor, acceleration sensor, body height sensor, roll angle sensor, rotation angle sensor, etc. Classification of sensor working principle Physical sensors apply physical effects, such as piezoelectric effect, magnetostrictive phenomenon, ionization, polarization, thermoelectric, photoelectric, magnetoelectric and other effects. Small changes in the measured signal amount will be converted into electrical signals. Chemical sensors include sensors with chemical adsorption, electrochemical reaction and other phenomena as causal relations, and small changes in the measured signal amount will also be converted into electrical signals. Some sensors can neither be classified as physical sensors nor as chemical sensors.
