Here we come to know about the main sensor on the car. Air flow sensor is the sucked air into electrical signals supplied to the electronic control unit (ECU) classification of automotive sensors, the basic fuel injection signal as one of the decision. Depending on the measuring principle, can be divided into the rotor blades air flow sensor, Karman vortex air flow sensor tours, hot air flow sensor and the hot film air flow sensor four types. The first two for both volume flow type, after the mass flow type. The main use of hot air flow sensor and two kinds of hot-film air flow sensor. Automotive Sensors - Temperature sensors are used to detect the engine temperature, suction gas temperature, cooling water temperature, fuel temperature, and the catalytic temperature. Temperature sensors have wound resistance, thermal resistance and thermal resistance even three main types. Three types of sensors have their own characteristics, its applications are also slightly different. High precision wirewound resistive temperature sensors, but the response is poor; thermistor temperature sensor with high sensitivity and response characteristics of a good, but poor linearity, lower temperature adaptation; high precision thermocouple resistance temperature sensor to measure temperature offer a wide range of automotive sensors, but the need to meet the amplifier and the cold side handle together. Products have been practical thermistor temperature sensor (Universal -50 ℃ ~ 130 ℃, 1.5% accuracy, response time 10ms; High temperature 600 ℃ ~ 1000 ℃, 5% accuracy automotive sensors which, response time 10ms) , ferrite type temperature sensor (ON / OFF type, -40 ℃ ~ 120 ℃ automotive sensors, precision 2.0%), metal or semiconductor film air temperature sensor (-40 ℃ ~ 150 ℃, precision 2.0%, 5%, the response time 20ms) and the like.
