Why do automotive electronic sensors need waterproof vents

In order to ensure the normal driving of the car, people convert the information of various working conditions in the running of the car, such as the speed of the vehicle, the temperature of various media, and the operating conditions of the engine, into electrical signals and send them to the car controller (such as a computer, etc.), so that the engine is in In the best working state, these signals are collectively referred to as automotive sensors. One of the characteristics of modern automotive technology development is that more and more components are electronically controlled.

In order to prevent the electronic sensor from being infested by dust, oil, and water, many automotive electronic sensors are currently equipped with waterproof vents to improve the protection of the sensing products. The protection performance can reach IP6K9K, and at the same time, it can release gas, balance the air pressure, and improve the reliability of electronic products in harsh environments. Choosing a good car sensor can improve the quality and safety factor of car products, and bring happiness to others!
