The greater role of the car sensor housing is a physical one. As an electronic packaging housing, it can improve the protection level of the sensor and prevent external water, oil, dust, debris, etc. from affecting the performance and service life of the sensor. At the same time, it also has the function of anti-shock, which prevents damage to the sensor when the sensor is slightly impacted by external force. The impact-proof effect of the metal shell is better than that of the plastic shell, and it also has a good anti-interference effect to prevent external electromagnetic interference from affecting the measurement.

　　The metal casing of the automobile sensor belongs to the test control system, which can feel the data information of the test measurement, and convert this data information into electronic signals or other data information conversion required by the corresponding basic laws. The system realizes automatic detection and automatic control. The vehicle-mounted sensor system transforms the speed of the vehicle and the ambient temperature of a variety of media into a computer network for sending electrical signals.

　　With the development of technology, automotive sensors are increasingly inseparable from people's daily lives. A car has various types of sensors. It is like our eyes, flowers, nose, and skin. The computer system allows the car to make correct judgments and assists the driver to better control the vehicle. With the advancement and development of technology, there will be more and more sensors in cars, and cars are becoming more and more intelligent. As long as the driver gives his own operating intentions, the rest will be handed over to the car.
