Composition of the sensor
Sensitive component: a component that directly senses the measured value and outputs a certain physical quantity that has a definite relationship with the measured value. Conversion element: the core element of the sensor, which takes the output of the sensitive element as input and converts the sensed non-electricity into an electrical signal output. The conversion element itself can be used as a stand-alone sensor, called an element sensor. Conversion circuit: the relevant circuits involved in converting the electrical signal output by the sensing element into useful electrical signals that are convenient for processing, control, recording and display. Auxiliary power supply: Conversion elements and conversion circuits generally require auxiliary power supply.
Automotive sensors are devices that convert non-electrical signals into electrical signals and transmit various working condition information to the vehicle. Automotive sensors can be divided into body perception sensors and environment perception sensors according to the purpose of use. The body perception sensor improves the informatization level of the bicycle itself, so that the vehicle has the ability to perceive itself; according to the input to be measured, it is mainly divided into pressure sensors, position sensors, temperature sensors, linear acceleration sensors, angular acceleration sensors, air flow sensors, Gas sensors, from the working principle, most of these sensors use MEMS solutions. The environmental perception sensor realizes the ability of the bicycle to perceive the external environment, helps the car computer to obtain environmental information and make planning decisions, and provides support for the intelligent driving of the vehicle; the environmental perception sensor is mainly divided into vehicle cameras, ultrasonic radar, millimeter wave radar, laser Radar and infrared radar etc.
