Automotive brake wear sensors are electronic devices integrated into a vehicles braking system to monitor the condition of brake pads. Their primary function is to detect when the brake pads have worn down to a certain level and alert the driver-typically through a dashboard warning light-so that timely maintenance or replacement can be performed. These sensors help enhance vehicle safety, reduce the risk of brake failure, and support efficient maintenance scheduling.

Automotive camera-based side mirrors, also known as digital side mirrors or virtual mirrors, replace traditional side mirrors with cameras and displays. These systems use high-resolution cameras mounted on the exterior of the vehicle to capture real-time video footage of the surrounding area. The video feed is then displayed on screens located inside the car, typically on the A-pillars or dashboard. This technology enhances visibility by reducing blind spots and providing a wider field of view, especially in low-light conditions or adverse weather

An air quality sensor is a device used to detect the concentration of pollutants in the air. It can usually measure two or more air quality indicators, such as temperature, humidity, carbon dioxide, carbon monoxide, ozone, formaldehyde, benzene, PM2.5, PM10, etc. It is an important part of the air purifier and fresh air system. Further, the air quality sensor's working principle is to detect gas and particulate matter indicators in the air through optical, electrical, thermal, and other methods.

A centrifugal compressor is a turbo or dynamic compressor with a radial design. It works by increasing the kinetic energy of the gas with a high-speed impeller and converting the kinetic energy into increased pressure in a divergent outlet passage. It is widely used for compressing large volumes of gas to moderate pressures. The main characteristics of a centrifugal compressor are a constant flow of fluids, constant-pressure functioning, and enhanced performance in extreme conditions such as changes in inlet temperatures. It is widely used in automobiles, oil and gas, natural-gas processing, refrigeration, air-conditioning, and heating, ventilation, and air conditioning (HVAC).
