Sensor Applications

The application of automotive sensors is very extensive, such as:
1. The gasoline indicator is achieved through a liquid level sensor, which converts the high and low liquid level into a digital signal and can be easily read from the instrument panel
2. Water temperature sensor: The water temperature sensor is a temperature measurement node installed in the water tank. When the water temperature is too high or too low, it can also give an alarm and can be directly read from the display instrument.
3. The interior air conditioning is controlled by a temperature sensor installed in the car. The temperature sensor has a temperature setting that automatically starts when the temperature is too low, and automatically cools down when the temperature exceeds the limit
4. Wiper sensor. The wiper senses the size of rainwater through the sensor, thereby controlling the frequency of the wiper. This means that when the rainwater is heavy, it wipes quickly, and when the rainwater is small, it wipes slowly.
5. The engine management system uses various sensors to convert the intake air volume, cooling water temperature, engine speed, and acceleration/deceleration into electrical signals, which are sent to the controller. The controller compares this information with stored information, accurately calculates it, and outputs control signals. EMS not only accurately controls fuel supply to replace traditional carburetors, but also controls ignition advance angle and idle air flow, greatly improving engine performance.
6. Control system principle: By installing a pedal sensor on the accelerator pedal, the pedal information is transmitted to the throttle control module in the electronic controller. The throttle control module calculates the throttle opening through a certain processing program and drives a DC motor to adjust the intake channel area of the throttle, thereby controlling the intake volume and meeting the intake needs of the engine under different working conditions.
